The District is very pet and family friendly. You will see children running around on the soft foamy play areas and people walking their dogs throughout the day. It is a great place to sit, have coffee, and talk with friends. The atmosphere reads more for the thirty to forty year old than teens and twenty year old crowd. The stores are geared towards people with a family to take care of and a house to decorate.
The highlight for someone around my age is the restaurants. Elephant Bar, Lucille's, and Balboa Pizza Kitchen have good happy hours. I know for sure that Lucille's has an early and reverse happy hour. My friend says that Elephant Bar has a late happy hour because she can make it after she gets out of work at 9. I could swear that Balboa had a late happy hour after 11 as well because there was nothing better after a ridiculous day than to get a few drinks, a salad, a pizza, and let out your frustrations with a few co-workers.
