It’s not the offices themselves in the Old Post Office that are worthy of jealousy; it’s all the nonwork accessories that the building has to offer. Built in 1899, the historic Romanesque building has a prime location on Pennsylvania Avenue near some hot restaurants and bars and theaters and shopping, allowing plenty to do over lunch breaks or happy hours. The Old Post Office is a tourist attraction, which certainly has some downsides, but it also means there’s a food court (sure beats the snack machine in most offices) and some shops (good for emergencies, like, oh, forgetting your anniversary). And let’s say you’re having one of those days and need to get away: Just blend in with those tourists and go to the top of the 315-foot-high clock tower. You’ll get an escape, plus a lovely panoramic view of the city.
