Spotted Cow, Hanoi
This is a favourite expat place, and great for kicking off a night on the town. Friendly staff, cold beer, and a great plce to meet people. You won't find more casual than this.
Dress Code: Short of being naked, anything goes.
We visited this place in our first night in Hanoi. Great food and nice atmosphere. Full of expats, and tourists. A nice place to have a Hanoi beer.
