What People are Saying

“This is what heaven must be like”

I travel to Key West a lot. It is a lovely town with lots of good restaurants. The seaside café has turned into my favorite spot to dine for lunch. The pizza is thin crust and similar to a new haven style.…….

…But what put me over the edge was the Prosciutto Caprese sandwich: mozzarella, prosciutto, balsamic tomatoes, arugula, and basil aioli on homemade bread that’s baked when you order your sandwich. Bread baked to order—are you kidding me? Run—do not walk—to the Seaside Cafe….. “

“Pleasantly Surprised”

…The food was spectacular and will take you on a journey of taste! From the finest pizza in Key West to the honey butter lobster biscuit to the truffle fries that come with a perfectly balanced basil aioli dipping sauce. Can’t wait to go back….
