Obviously we're all here because we love food. I enjoy nothing more than going to a restaurant, and getting much more than I expected. Beit service, food, or atmosphere.
At the same time, I hate it, when you spend a significant amount of money, and get poor service, food, or otherwise. Especially coming out thinking "I could've gotten better food for 1/5 the price at Jack Astors". Which is why I suppose we're all here...to avoid the big box restaurants.
So..your most disappointing places (places we should avoid), and most surprising places (those gems)?
