I did some exploring in my old neighborhood the other day. I used to live in Adams Morgan/Columbia Heights/Mt.Pleasant neighborhood in DC a few years back when the neighborhood was turning from modestly inexpensive to gentrified and pricey. They are three separate neighborhoods but that are often seen as one whole neighborhood. This area of DC is the most densely populated, diverse and best part of DC. It has trees, parks, office buildings, churches, mosques, temples, everything and anything.
There is always something to do in this neighborhood; you could go to the park, the zoo was nearby, there are hundreds of restaurants, bars and a couple of clubs, the area is full of cultural centers and different religious organizations and I believe this area is one of the most racially diverse in the DC area and not just that you will see people of different races coming together, being friends, intermarrying. This areas also is great for walking and it's close to Columbia Heights and DuPont Circle metro stations. If money grew on trees I would love to live in one of the pre-war apartments that can be found in this area.
I went into the Tibet Shop, basically a Himalayan shop that sells clothing, furniture, fabric, jewelry and other crafts from Asia. Here are some pics I took:
