This place is not the famed Little Hanoi of Lonely Planet, but another one sprouted up to take advantage of the popularity of the first. There are in fact three Little Hanois in Hanoi. This is the only one on Hang Gai street, convenient to the silk dress shops. It is also a great place to eat before going to the Thanh Long Puppet Theater, or before a stroll around the lake.
Little Hanoi is an upscale cafe serving mainly westerners in a pleasantly lit restaurant. They serve French snack food, including croques and quiche. You can also get a western breakfast. We enjoyed the mixed spring rolls the most, and I was happy to have a quiche after so long in Asia. Little Hanoi has a full bar and a nice selection of teas.
No reservations were required in the low season of September. There were plenty of seats, but it did appear to be a popular restaurant.
