Wordbones posted about places to watch the World Cup on Tales of Two Cities -- specifically Looney's in Fulton that is showing every game and Trattoria Amore in Columbia that hosts World Cup viewing parties. Looney's is even opening for the early games and serving breakfast.
I bet that you could have real fun watching a South Korean game over beer and fried chicken at Rainpia on Rte 40 in Ellicott City. Or maybe barbecue at Shin Chon Garden. Both joints show Korean television in their dining rooms, so I assume they'll show South Korean games.
Any other suggestions? Feel free to promote your local.
