Unfortunately, I will be at work for the game -- can't get away, either.
My recommendations for watching are:
Lucky Bar (Connecticut Ave & M street) - good atmosphere, owned by a United fan so VERY EPL
FADO (7th street in Chinatown, just north of the Starbucks) - Irish pub, mostly epl but decent pub food
Elephant & Castle (12th & Penn) - forgot about this place. Supposedly the designated Liga pub in DC.
