Man that is like pullin hen's teeth. They just give me this dumbfound look, then look up at the existing menu and say that looks good enough for me. That is the whole reason why I posted up this thread.
Ah, that would pose a problem...
In that case, I'm a fan of seafood and since you have a ton of fishes at your restaurant I think that a seafood-based menu could work great. You could have shrimp and a couple kinds of fish plus have daily/weekly features such as crab, scallops, lobster, squid, and/or octopus. The lobster and crab could be a once a month/week thing that could draw in a bunch of people since people love both of those foods. You'd have to have some non-seafood items for the non-seafood eaters, but those could have a sea-related spin on them, too (sea-salt on fries, etc.). Basically I'm thinking fast food seafood with the taste and quality of sit-down seafood.
Do you have a specific number of items (appetizers, main courses, etc.) that you're looking to offer on the menu?
