It's my favorite sports time again, March Madness, and there are games on all day today and this weekend. I was trying to think of places to go to watch the games in the hood -- there aren't many, but there are a few. CommonWealth has TVs, but the bar area can be crowded at happy hour time, so you might want to get there early. I'm guessing Ruby Tuesday does as well, though to be honest I've never been in there. In addition, The Heights has some TVs over the bar. So you can watch your local teams in the hood, like Maryland (unfortunately VCU and American lost close ones), or your away teams.
Wonderland and the Red Derby don't have TVs, so don't try there. U Street and Mt. Pleasant would also have some opportunities, plus lots in Adams Morgan.
