I went to this tavern last night and had a great time. The people I met there were very nice and unpretentious. Karaoke was going on, and the crowd was very enthusiastic. The bartenders were nice, too. I am definintely going back sometime, and I can't believe it too me so long to discover this place considering I've been in Seattle for over 10 years.
Pros: You can meet new friends immediately and it's not "sceney"
Cons: None that I can think of
