    We ordered the soft shell crabs here because we've learned that Seafood Unlimited knows how to prepare them. These delicately-flavored crabs come sautéed with very light breading; consequently, one tastes the delicious car, not a heavy coating of fried dough. Served atop spinach risotto, also delicate in flavor for a perfect complement, the dinner was expertly prepared, served efficiently, and was thoroughly enjoyable. This small, neighborhood gem does seafood right, is fairly priced, and is a local business run for years in a quality way. We recommend it without qualifications.

    Nothing really to brag home about. The food was ok, sort of generic standard menu at a fish eatery. Nothing on the menu stands out or tastes like it would make you want to go back. The service was nice, ambiance was good.

    There is a reason I've been eating at Seafood Unlimited for over 40 years. it's really, really good. Neighborhood elegant; terrific food, wonderful staff, great owners who care about every diner and every meal, delicious drinks... there is no reason not to make this place a favorite for every reason. Special occasion, dinner with friends or just a good meal after work; the restaurant succeeds on every level.

    We’ve been coming here for eight years now. It is always amazing and delicious. Judy and David are wonderful hosts. We had the buck a shuck oysters, which were great. For entrees we had the fried sea bass and the stripped bass. They were both amazing. The value was terrific. Ryan, our server was wonderful. Well done.
