When it's warm outside and your throat is parched, order up a limeade. Sweet tea is the soft drink of the south, and you can get that here in Richmond. But something slightly more Richmond is limeade which you can get at many restaurants in town. If made correctly it is on the tart side and much less sweet than lemonade. Some places you can get it that I know of are Comfort and all Bill's Barbeque locations.
Get one and try it... you won't be sorry!
