Heavenly Biscuit is one of those great, small locally owned restaurants. They do great food, concentrating mainly on breakfast (but they do small a small number of lunch options as well). It’s tucked just off of Estero Blvd, down a bit from Diamondhead resort. There is very little street parking, so often it can be best to park up off the beach (we walk from Bowditch and stop for breakfast) and walk in. During season it’s standing room only from r breakfast, best to be there shortly after it opens. The biscuit sandwiches are killer and huge, and the cinnamon rolls to die for. You get in line, place your order and they come find you later - paying is on your honor, and please don’t skip out on these guys. They care about the food they serve and it shows. It’s just great homemade fare.
