Where are some good places to get a beach chair/seat and drink/snack on the beach (used to use For Real bar/23-7/Boat Bar)?
Boat Bar; BarBBarn; Treehouse are my favorites.

Where are some good (inexpensive and teen friendly) places to eat, relax and visit while on the West End?
Xtabi; Canoe; Three Dives - for cheap eats though I would check for local box lunches or patties (Choices on West End, Juicy Js in town.)
