My days as a Hoya are too long ago to remember much about the food (there really wasn't much good food there then-from a Louisiana perspective), but one of my favorite bars in the world is the Tune Inn, at 331 1/2 Pennsylvania S.E. I also spent plenty of time at the Dubliner and Irish Times near Georgetown Law School (which is not near Georgetown), and Hawk & Dove and Bullfeathers on the hill. Ruth's Chris Steak House was on Connecticut Ave., N.W.
Have fun!
