My favorite Vietnamese restaurant when visiting Toronto from New York. I typically always get these two usuals
1 - 7 Course Beef
Order only if you can really eat a lot of food...usually for group eating
Also quite hands on as you are eating lots of wraps using Rice paper, lettuce and of course different versions of cooked beef.
2 - Durian milkshake
Its like heaven =)
Spring rolls are good too.
Not sure about all the other poor reviews about the Pho beef noodle soup as I've never tried it. Everytime I'm in town from Buffalo, NY and bring friends, they are rave about the 7 course beef too!
