- Lucas: So last week I was at a seafood spot outside Portland, Maine, not a fancy place, think picnic tables and paper napkins, and I watched a guy at the next table order the lobster roll. It was twenty-nine dollars, market price. The server came back and said 'Sorry, today it's thirty-four.' The guy shrugged and said okay. Luna: And you were watching him like a hawk, I assume. Lucas: I was timing how long it took him to finish it. And I got thinking about the math behind that plate. Because that server essentially just raised the price by seventeen percent mid-order, and nobody blinked. But the thing is, that restaurant might actually be losing money on that lobster roll. Luna: Wait, thirty-four dollars and they're losing money? How is that possible? Lucas: Because the cost of the raw lobster has been volatile. In early 2026, we're seeing wholesale lobster prices around eleven to fourteen dollars per pound for a one-and-a-quarter-pound hard-shell. But a lobster roll isn't just one lobster. A typical roll uses about four ounces of picked meat. To get four ounces of cooked meat, you need roughly a one-and-a-half-pound live lobster, because you lose about forty percent in shell, water, and cooking shrinkage. Luna: So the actual food cost for the meat alone is maybe seven, eight bucks. That's not terrible. Lucas: It's not the meat that kills you, it's the yield variability. If that chef gets a batch of lobsters that are light on meat, say a pound and a quarter instead of a pound and a half, they need more lobsters per roll. Plus there's the labor to pick the meat. A skilled picker can do maybe eight pounds of meat per hour, and they're making eighteen to twenty an hour in that market. So you've got another two to three dollars in prep labor per roll. Luna: And then the bun, the butter, the fries on the side. Lucas: Exactly. And the plate waste. I talked to the owner after my meal, and he said on a busy Saturday they'll throw away five to ten percent of the picked meat because it sits too long in the warmer and dries out. That's pure loss. So their actual cost per lobster roll, including everything, landed around seventeen to eighteen dollars. On a thirty-four-dollar sale, that's a food cost of about fifty-three percent. Luna: Fifty-three percent is terrible. Most restaurants target twenty-eight to thirty-five percent food cost. Lucas: Right. So that lobster roll is a loss leader disguised as a premium item. Meanwhile, the fried fish sandwich at the same restaurant, made with frozen Atlantic cod, costs them about one-seventy per portion. They sell it for fourteen dollars. That's a twelve percent food cost. That sandwich is subsidizing the lobster. Luna: So the cod and the shrimp are the real profit centers. But the lobster is what brings people in the door. Lucas: Exactly. It's a halo item. And I think a lot of operators don't actually run the full yield and labor math on their seafood. They look at the invoice cost per pound and think they're fine. But they're not accounting for the fact that a three-pound lobster, which sounds impressive, actually has a lower meat to shell ratio than a one-and-a-quarter-pound lobster. The bigger the lobster, the more shell you're paying for. Luna: So the jumbo lobster on the menu is actually worse for margins than the smaller ones? Lucas: Often, yes. I've seen data from a New England chain that tested a 'market price' lobster roll in 2025. They tracked every variable for three months. Their food cost on the roll averaged forty-seven percent, but on weeks when they got a shipment of three-pounders, it spiked to fifty-eight percent. They eventually switched to a fixed price and a smaller portion, which actually improved customer satisfaction because the price was predictable. Luna: That's counterintuitive. You'd think customers would feel cheated getting a smaller portion for the same price. Lucas: Turns out they hate the uncertainty of market price more than they hate a slightly smaller roll. That chain saw a twelve percent increase in lobster roll orders after they fixed the price and portion. The margin went from breakeven to a healthy thirty percent food cost. Luna: That's a great example of why menu engineering matters. So if I'm a restaurant owner, what's the one seafood item I should be pushing for profit? Lucas: Fried shrimp. Specifically, the butterfly shrimp you buy frozen, breaded, and ready to fry. The food cost is absurdly low. A six-ounce portion costs maybe ninety cents. Sell it for twelve to fourteen dollars as an appetizer. That's a six percent food cost. And customers perceive it as a treat. Shrimp has that luxury halo without the actual cost. Luna: And the prep labor is almost zero because it's frozen and pre-breaded. Just drop it in the fryer. Lucas: Right. Compare that to fresh shrimp, which you have to peel and devein. Even if you buy peeled and deveined, you're paying a premium. The frozen pre-breaded stuff is where the margin lives. There's a reason every casual seafood chain in America has a fried shrimp basket. Luna: So the takeaway for operators is: know your yield, know your labor, and don't let the lobster seduce you. Lucas: Exactly. And if you're going to run a halo item like lobster, run the numbers every week, not just when you set the menu. Because the wholesale price of lobster can swing three dollars a pound between March and June. That's the difference between a forty percent food cost and a sixty percent one. Luna: You know, this kind of granular detail is why I love doing this show. We spend a lot of time digging into the real numbers that most operators don't talk about. Lucas: It's exactly why we keep the show free of ads. We want to be able to say whatever the data shows without worrying about a sponsor's feelings. If these conversations have helped you think differently about your own numbers, we'd love it if you considered supporting the show. Luna: Yeah, we don't run any ads on these episodes. It's a choice. And listener support is what makes that possible. Lucas: If that matters to you, the link is buy me a coffee dot com slash fexingo. No pressure. Now, back to seafood. I want to talk about another item that's quietly killing margins: the whole fish. Luna: Oh, the whole branzino presentation. I see that on menus everywhere these days. Lucas: Right. It looks impressive, and it commands a premium price, usually thirty-five to forty-five dollars. But the yield on a whole fish is about forty-five to fifty percent after you remove bones, head, and skin. So a one-pound whole branzino at seven dollars wholesale gives you maybe half a pound of edible meat. That's an effective cost of fourteen dollars per pound of meat, before any prep labor. Luna: And the labor to debone and plate it is significant. You need a skilled cook. Lucas: Exactly. And the plate waste is higher because customers often leave the tail and the head untouched. I've seen studies that show twenty to thirty percent of a whole fish plate goes to the trash. So the real food cost on whole fish can hit forty-five to fifty percent, similar to the lobster roll. But the perceived value is high, so customers feel good about it. Luna: So it's another halo item. But what if you want to actually make money on seafood? What's the best approach? Lucas: I think the smartest strategy is to have one high-margin workhorse item, like fried shrimp or fish and chips made with frozen cod, and one high-perceived-value item that you manage carefully. And then you cross-utilize. For example, use the shrimp in a po' boy at lunch and as an appetizer at dinner. That way you buy in volume and reduce waste. Luna: And if you're doing a raw bar, oysters are interesting. The markup is huge, but the shucking labor is intense. Lucas: Oysters are a whole other rabbit hole. The wholesale cost of oysters has been rising, partly because of climate change affecting growing regions. In 2026, Gulf oysters are running around forty to fifty cents each wholesale. A restaurant might sell them for two to three dollars each. That's a great markup, but a skilled shucker can do maybe a hundred oysters per hour and costs twenty dollars an hour. So you've got twenty cents labor per oyster. Plus the setup and cleanup time. Net food cost around thirty percent, which is decent but not amazing. Luna: So the real winner might be the simple fried shrimp basket. Low labor, low waste, high perceived value. Lucas: That's what the data says. But I'll also say this: the restaurant that nails its seafood program is the one that treats the supply chain as a daily variable, not a static cost. They're checking the market every morning and adjusting the menu special accordingly. The ones that print a static menu and stick to it for six months are the ones getting crushed when lobster spikes. Luna: So the bottom line is: know your yield, know your labor, and be ready to pivot. That sounds like good advice for any part of the menu, not just seafood. Lucas: Absolutely. But seafood is where the margin trap is most hidden because the raw numbers look good until you account for everything else. I think next time you're at a restaurant and you see a 'market price' lobster, you'll know exactly what's happening behind the pass. Luna: And you'll order the fried shrimp instead. Lucas: I might order both. But I'll know which one is paying the rent.
