My husband and I are both foodies and will be visiting my non-foodie grandparents for a week in the St. Pete area. My grandparents don't appreciate fine dining so much and will have a cow if anything is too expensive (even if someone else picks up the tab). So, any recs for great cheap or moderately priced eats in the area? Also, I plan on doing some cooking while I'm there as well. Are there any farmer's markets in the area, or great markets in general. I know there must be some great local fish in the area!
