For the next game, check to see if the Mosaic Center and Washington Harbor are showing the match, if you're interested.
This mentions Washington Harbor http://www.pressboxdc.com/2014/06/24/world-cup-generating-business-excitement-and-big-crowds#close Mosaic District is showing the Belgium game. Picture above is Mosaic District.
and there will also be a viewing at the National Portrait Gallery enclosed courtyard for those that would prefer to no watch in 90 degree weather
The Freedom Plaza viewing was getting pimped on radio this morning. It's cool how the US is catching this World Cup Fever thing. Hell, my office is showing the game the in the "pre-function" area.
