Well, its not full of idiot expats, I assure you.
Its a 6 ft long bamboo bar, in an edge of a parking lot about a 3 minute walk in on Sukhumvit 11 on the left side. Has about 10 stools and all the beer is in an ice cooler (50 bht each). Its a fun little place to grab a beer, and if you are hungry there are 2 Indian resturants about 15 paces away, and a really crappy english pub about 40 paces away. I always stay in the hostel right there, $17 bucks gets me a private room, king size bed, an ensuite bathroom and free breakfast, plus free internet, tv and a great rooftop garden.
Those can be fun also. :) Let me know next time you are in town and I will see if I can make it.
