Hanoi can be hit and miss as far as dining options go. It's not cool to over plan but visitors could benefit from reading about the experiences of others that have been and done it before. The two foremost resources on the Hanoi dining scene are ChefMoz: Restaurants in Hanoi and  NewHanoian. Both of these resources contain extensive listings and both allow customers to rate restaurants and post reviews.

The blogosphere also features some great resources, with the king of the crop probably being StickyRice. This blog brings the food alive with excellent photos and extensive background information on featured establishments. The old favourite Noodlepie also has a Hanoi section.
