There is a pool bar at Dante's in the Key West Historic Seaport (the old Toxic Triangle) which is free for all with or without buying any food or drinks. The Artisan Market isn't really a farmers market more like a craft show but worthwhile either way. There is a farmer-like market on Stock Island, The Grove on 1st street behind Roostica Pizza open Friday and Saturday, I think. For Key Lime pie cooking ask Martin Liz at the Lost Kitchen Supper Club also on Stock island. If he doesn't he would know.
