Sreeet & Co. seems to be the automatic response to anyone loking for a nice seafood restaurant in Portland. I like Street & Co, but I want to put in a plug for the Old Port Sea Grill on Commercial Street. My wife and I have eaten there 3 times in the last couple of months and we've been impressed--great seafood prepared really well. I know that the best way to eat steamers is on a pier in the summer, but I had the best steamers ever at the Sea Grill--amazingly fresh, sweet and clean. The atmosphere is more sleek/modern than cozy, and the prices are more than moderate, but service is great and everything I've had there was very good.
