I've pretty much have had every dish possible and have been coming here since I was a child. A few of my favourites off the top of my head...
-avocado milkshake
-pho with beef balls and rare beef
-chicken pho
-banh cuon
-spring rolls (or egg rolls, whatever you want to call it)
-com tam
This place is small for the amount of customers dining and waiting to get into the restaurant. I think that should tell you how good this place is.
