Don't be fooled to have dinner in the Lobster pot or even the Baya Hub next door. If you like good food you should head directly to the Cottage. It's the best food I had in Siesta Key and without the touristy prices too.
Try any of their cheviches or their gorgeous steamed black mussels in a spicy broth with buttery garlic bread. On happy hour you'll just pay about 7 dollars for that and 2 for the beer.
The ambience is great too and they have a cozy outdoor setting.
