The A&B Lobster House is the upstairs sister bar of Alonzo's. While normally I wouldn't write two reviews for what is essentially the same restaurant, they actually have completely different menus, and their own very distinct and different atmospheres.
The menu at the A&B is mouth watering and elegant. Where you can order a burger downstairs at Alonzo's, you can dine on escargot and caviar upstairs in the A&B Lobster House.
I found the place to be beautifully decorated and extremely clean with a lot of emphasis on class. They even have a smaller area called Berlin's Bar where you can purchase and smoke fine cigars while enjoying your favorite cocktail.
While they are a family friendly restaurant I would not say that this is the best place for small children. This place is perfectly suited for an anniversary dinner or perhaps a date with someone special who you hope to someday have an anniversary dinner with.
