A & B lobster house is one of the best steak and seafood restaurants in key west. the name is an abrevation of it's founder's names, alonzo and berlin. they specialize in steaks, maine and florida lobster. they also have an excellent selection of local seafood. this two story restaurant has an oyster bar on the first floor, a cigar bar, and the main restaurant on the second floor.
There are a lot of great ones ! I recommend, the Commodore on harbor walk, A and B lobster house (next door to Commodore) Louie's back yard..on the Atlantic side, Ambrosia which is Japanese but has excellent sushi prepared from local fish
Restaurants are a little pricey, but you definitely have excellent quality choices of local sea food which is definitely as fresh as it gets
Favorite Dish: Yellow fin Tuna (rare), snapper, Margueritta's, key lime pie
Located at the end of Front Street A&B Lobsterhouse is an upscale restaurant offering some of the best seafood you will find. It's all fresh and it's prepared in unique ways. If you want to take a break from Key West this is the place to go. They have an excellent wine list to accompany the food.
Favorite Dish: The special when I was there was Porkfish that had been caught in the Tortugas. The waiter said it was considered a delicacy because of it's taste. It was a very light fish that melted in your mouth. It was excellent. The Lobster bisque was also excellent.
Located on the water in the marina area the A&B is on the second floor with great views of the yachts in the harbor. While Key West "clothing" is typically VERY casual, the A&B tends to the more well dressed crowd.
Their menu prices reflect the "theme." There is a dish to please most anyone but it comes at a cost. The wine list is relatively extensive for Key West, but at almost triple markup in some cases the selection is not that good.
Favorite Dish: Actually nothing we ate was remarkable. It was ok, but not for the price.
