My wife and I frequently go to a korean bar called Ehwa, next to the Artful Dodger on Isabella St. Its a busy place at night with two floors and a surprisingly nice patio. Downstairs looks like a dark dingy bar and the upstairs looks like a library study room. It gets busy later on in the evening/night and is populated almost entirely with korean students.
We always go for one of the combos $22-$28 for a main dish and 4 beers or 1 bottle of soju. Instead of the regular banchan you get at a korean restaurant, you get popcorn, costco fries, some mayo/corn thing, some tofu, and cabbage coleslaw.
Its a fun place to drink with food that is all pretty good.
