Choptank is not at all formal but its definitely a notch above a classic food shack. As you may expect, the fish-heavy menu includes crab, oysters, peel and eat shrimp, and various white fish. I sampled the fish tacos to start (the most popular menu item) and then couldnt resist the crab sandwich. Both were excellent, with good flavoring. I would definitely eat here again.
Service also was very good, and Choptank has a fine wine selection. In the back, there is a small outdoor area which is pleasant for eating outside. The crowd is decidedly smart and attractive, as one would expect at a new-ish trendy place in Manhattan. The value here is pretty good. However, if you are really hungry, come on a Sunday when you can order up an all-you-can-eat crab meal for $65.
