Key West is blessed to have several excellent bakeries, here are my suggestions for your wedding cake and sweets:
A small family owned bakery at the corner of Grinnel and Eaton Streets. Owned by Niall and Elsa Bowen, Old Town Bakery consistently is highly rated on Trip Advisor. Download OLD TOWN BAKERY Wedding Cakes
Located in the 800 block of Duval, this very busy place continues to impress as it serves both breakfast, lunch and dinner daily. The bakery includes a master baker and designer. Croissants is where I had my first meal during my first visit over Christmas in 1989.
Owned by a French couple, this intimate little cafe doesn't offer wedding cakes, but they do have wonderfully tasty croissants and other baked goods. They are open daily from 7am to 3pm. Worth a visit, especially if you're staying on the Atlantic side. On United St. 1/2 block from Duval St. across from the Southernmost Hotel
