Among the many ridiculous questions servers ask is, “Is (insert menu item here) good?” I mean, what do you think we’re going to say? “No. That’s straight trash.”
Patrons, just read over the menu and pick something you want. You’re visiting a restaurant to eat the food the way they prepare it. If you don’t like it, pick something different next time. Whether something is “good” or not, is personal and subjective. I just met you. I don’t know what you like. I don’t know how you like food prepared.
Probably the worst thing you can do is ask if a dish is any good when it’s a food you’ve never eaten before. Do you really want to drop $20 or $30 on food you might be afraid to take a bite of? In this instance, asking me if it’s “any good” is going to serve absolutely no purpose. Don’t do it.
The restaurant I work at makes seafood dishes. I hate seafood. When a table asks me if a seafood dish is any good, I tell them it’s great. You’ll really like it. It might be the best thing on the menu. The only exception to this is when it’s a cheap item. I will likely try to get you to buy a more expensive dish.
