I've checked out a new pub/cafe named May at 2 Nam Ngư St. Although it's on the second floor meaning you have to take some stairs up, what i've found is quite interesting. The place is quite small but very friendly. They have pictures of film stars and good old Hanoi on the walls. There's an unused fireplace at one corner but i was just having fun with the pool table at the center of the room. Warm lightings and cold beers and they keep the area cool which really helps in this kind of weather. There's nothing special about the music but they will play the songs you request and the volume was reasonable unlike other places. The owner, Phuong, was very nice to me. I think it's a good place for meet-up, grab a drink and have a fun time.
