world famous lobster pizza

The Seaside Cafe at the Southernmost Mansion is a family-owned and operated Island eatery just a few steps from the warm waters of the Atlantic Ocean.

A new addition to the Key West landscape, but already well known for island classics such as their Mansion Mojitos, Honey-Butter Lobster Biscuits, and stunning artisan wood-fired pizzas.

The Seaside Cafe is located on the grounds of Southernmost House, a charming Victorian mansion on the “quiet end” of Duval Street.

Come experience the hype around our wolrd famous lobster pizza

"Great mojitos & lobster pizza, When they say best mojitos and lobster pizza they mean it! We had a wonderful lunch and would gladly return. Good service!"
I wasn't leaving Key West without trying the lobster pizza that I've seen reviewed here. It was well worth it! And you can't beat the location. If you want a fresh, homemade margarita- this is the place!!
Yes the Lobster pizza really is that good
Worth a visit just for the atmosphere, views, and service, but the Lobster pizza is so good my mouth is watering now as I write this. So fresh. So tasty. So much flavor. If you come to Key West and don’t eat here, you didn’t really visit Key West.

Watch the sun go down while you sip on a freshly crafted mojito and enjoy our world-famous lobster pizza. Few venues offer such proximity to the reason so many call Key West home.
