The Red Derby is a new little bar at 14th and Spring in Petworth, and it's pretty cool. It has a good atmosphere, kinda neighborhoody and laid back, and they have beers only in cans, which is neat. It's cheaper, for one, and they have a good variety - everything from Natty Boh ($2) to Dale's Pale Ale to Brooklyn and Boddington's and Guinness. They also had some Belgian pilsner and a bunch of other things, with the most expensive being $5 or $6. Plus cans mean you won't get a skunky beer. The staff was really friendly and they have pretty good grub - fried macaroni and cheese, sweet potato fries, and the usual burger, chicken fingers, etc. There's a pool table in the back too. It's a neat place and I'd like to hang out there more often.
Red Rocks is a small pizza place at 11th and Park in Columbia Heights. It also has a nice atmosphere, with a few tables and a little bar, a patio, and I think a second floor (not sure). The pizzas were good, if a little stingy on ingredients - the pesto one didn't have much pesto, and the other one we got didn't have much meat. It was pretty good, but I prefer Radius or Matchbox. But it's close and nice.
