I'm a frequent customer, and I love the steamed chicken pho, pork bao/ vegeterian buns and the banh mi's are pretty good as well! The only thing is that they don't heat up their banh mi bread so it's always cold when you're looking for something warm to eat. They also have a good variety of cool asian drinks like mango juice and bannana cola which is awesome!
Also, in this location there are very few seats so expect to get it for takeout when you're in rush hours. This place is less stuffy and cleaner in my opinion than the one in the music building so I like to go here, but if you want a comfortable seat it's better to go to the one in the music building!
This place is good but Vua down on university serves cheaper, better banh mi in my opinion, but if you're lazy like me and like to stay on McGill campus, then this is the place to eat! :p
