I've never been a huge Vietnamese fan, but Rice Paper has shown me the light! This little joint is run by two sassy sisters who are a hoot to be around and make delicious food.
The spring rolls here are amazing - I think its the best thing on their menu - and they are so cheap that you can order several of them, tapas style! They are always made with fresh ingredients and are packed with flavor.
I also love the vegetarian pho. It may seem expensive but it is HUGE and comes with a number of ingredients - tofu, lime, mint, jalapenos, sprouts, onions. Whenever I am in a soup mood I turn to that pho.
