Bia Hoi Corner in the Old Quarter, Hanoi
Thanks to Lonely Planet, this corner is one of the most famous in the old town of Hanoi. There are fresh beer joints on all four points of this corner. Tourists flock here to drink beer for 3,000 VN dong ($1 is 18,000 VN dong) per glass. Its a little over-rated (i.e., touristy) but we met some really nice Vietnamese (and Korean) people here, and had some decent cheap beer!
