"Market price" on a seafood menu means the dish is priced by the current wholesale cost of that seafood. It's not a fixed number the restaurant printed once and left alone. You'll see it most often next to lobster, crab legs and other seafood whose cost really does move week to week, or even faster.
A menu that shows "MP" or "market price" instead of a dollar figure can feel cagey. Usually it's the opposite. Keeping a printed number accurate would mean reprinting the menu all the time, and nobody does that.
Why seafood cost moves more than other menu items
Most restaurant ingredients, like chicken, beef and produce, are farmed or grown. Their supply is fairly steady and predictable. Some seafood isn't like that. Wild-caught lobster, crab and some specialty fish depend on catch size, season, weather and fuel costs for the boats that bring them in. All of that moves the wholesale price more often, and more sharply, than a typical grocery ingredient.
A restaurant's cost for a pound of crab or lobster can change a lot from one week to the next. So a fixed menu price is a bet that will eventually go wrong. Market pricing removes that bet. It ties the menu price to the current cost.
What restaurants gain from market pricing
Restaurants use market pricing for two practical reasons: protecting their margin and avoiding reprinting costs. Reprinting a menu every time a seafood price shifts isn't realistic. So a restaurant has three choices. It can absorb the difference when costs rise. It can pad the price heavily to cover future swings. Or it can charge what the item costs right now and update it as needed. Market pricing is that third option. It keeps the price closest to what the ingredient is actually costing the restaurant.
This isn't unique to one restaurant or chain. It's a standard, long-standing practice across the industry. You see it most on seafood menus because that's where wild-caught sourcing and price swings show up most.
Why it can still feel uncomfortable as a diner
Being wary of a missing price is fair. It's a reasonable critique of market pricing, not a sign that something's being hidden. The honest answer is that a market-priced dish's cost really wasn't fixed when the menu was printed. That's the whole reason it's labeled that way.
The simple fix is to ask. Asking the current price of a market-priced dish before you order is a completely normal question at any restaurant that lists one. Your server should answer without hesitating. If a restaurant can't or won't tell you the price before you order, that's a more real concern than the label itself.
What tends to be market-priced, and what usually isn't
Lobster, whole or in some preparations, and crab legs are the most common market-priced items on seafood menus. Both are often wild-caught, so their supply swings more than farmed seafood. Some whole-fish or specialty dishes sold by weight show up this way too, especially when the portion size changes from plate to plate.
Shrimp, most fish fillets and other seafood from steadier supply chains are far more likely to have a fixed price. Their wholesale cost tends to move less, and less often. That's part of why a seafood menu can list market-priced lobster right next to a fixed-price shrimp dish. It reflects real differences in how each ingredient is sourced, not a muddled pricing policy.
How market price actually gets set
Market price isn't made up. It's usually based on what the restaurant is paying its supplier now, plus the same markup it uses on any other dish. If a restaurant pays more for crab this week than last week, it passes some or all of that increase along. In principle, a lower cost gets passed along too. In practice, prices tend to go up more readily than down. Restaurants are usually slower to cut a price than to raise one. But the idea is the same either way: the menu price follows the current wholesale cost.
That's also why market price can differ between locations of the same restaurant. Supply and shipping costs aren't the same everywhere. A location close to where seafood is landed may see smaller swings than one far inland, where shipping is a bigger, more variable part of the cost.
The difference between market price and a special or limited-time price
Market pricing is different from two things it's sometimes confused with. A limited-time promotional price, common for seasonal seafood offers, is a set price for a set period. It doesn't move with wholesale cost day to day. A market-priced item has no fixed window like that. Its price is whatever the current cost works out to on a given day or week.
Daily or weekly specials are related but separate, too. A special might feature a market-priced item because its cost happens to be low right then. That's one reason some seafood specials show up more in certain seasons. It's not just about freshness or availability. Often the ingredient is simply cheaper to buy at that time of year.
Why lobster in particular gets this treatment so often
Lobster is one of the most common market-priced items on seafood menus across the country. The reasons come down to how the industry works. Lobster is still almost entirely wild-caught. It's harvested by season and depends on weather, fuel costs for the boats and the size of the season's catch. All of that shifts faster and less predictably than farmed proteins. A cold snap, a strong or weak season, or a change in export demand can move wholesale lobster prices noticeably within weeks. A fixed menu price just can't keep up with that pace.
Crab shares many of the same pressures. That's part of why the two so often appear at market price side by side, while a farmed or steadier item nearby has a fixed number.
What this looks like on an actual seafood menu
Crab legs and whole lobster are the classic market-priced dishes at many seafood restaurants. A whole live lobster is often priced by weight and the current market, since each one is a different size. Red Lobster is an exception on its online menu. It prints fixed prices for Crab Your Way and its live Maine lobster, and updates them when its menu prices change.
Endless Shrimp and most shrimp and fish entrées have fixed prices almost everywhere. Shrimp and most fish come from steadier supply than wild lobster or crab. So seeing both pricing styles on one menu isn't a mixed message. It's the menu reflecting real differences in how each ingredient reaches the kitchen.
How to plan a budget around a market-priced meal
If cost matters to you, treat a market-priced item as an unknown to check, rather than skipping it. Call ahead, check the restaurant's website, or just ask when you sit down. None of those are unusual requests for a market-priced dish.
It also helps to set a limit in your head before you ask. If the server quotes a price above what you planned to spend, just order something else. That's not an awkward moment. It's exactly the choice market pricing is meant to let you make, with real information instead of a guess. A restaurant that lists a dish at market price expects some diners to ask and decide from there. It doesn't expect everyone to order it sight unseen.
If you're a regular somewhere, knowing a market-priced item's usual range over time helps too. Lobster and crab prices tend to follow a seasonal pattern rather than a random one. They're usually higher around certain holidays and busy times, and somewhat lower at the peak of a strong catch season. A menu won't say that. But it's part of why the same market-priced dish can cost quite different amounts depending on when you order it.
The short version
Market price isn't a trick or a way to dodge a commitment. It passes on what the restaurant is currently paying for that seafood, most often lobster or crab, where wild-caught supply really does swing enough to justify it. If the number matters to your budget, just ask before you order. At any restaurant with a market-priced dish, it's the expected question, not an awkward one. Asking up front is the simplest way to avoid a surprise on the bill.
