I think something like a walk up with an awning would be cool. If you had some type of covering on the side(s) and rear possibly with tables that would be pretty cool. Maybe a small bldg with a counter, and a high (15 feet or so) rigid canopy like a gas station over an area of picnic tables of to the side?
Sounds fun though. Good luck!
