I was at Jaleo in Penn Quarter last night and at the bar wines by the glass and beer are half price until 7. What's even better are the $4 tapas (not all but a decent assortment), most of which are $6-8 on the regular menu. The half price raw bar at Old Ebbit is an old favorite. I also understand Black Salt has good specials during happy hour although I haven't gotten over there for that. Are there any other worthwhile restaurants downtown offering good happy hour deals?
