No, the store is on G Street, between 9th and 10th IIRC. So smack in the middle of downtown, a scant two blocks from the FBI headquarters.
Penn Camera gave up on film users a long time ago. Now they're owned by Calumet, who is reorganizing the stores completely, so do expect some holes in the stock for a while until the transition is complete. They do still carry an ok range of 35mm film - you're in trouble if you want bigger, but that's been the case for the last half-dozen years.
