Delicious food at unbelievable prices. The pho is great, but if soup isn't enough to fill you up, they have really good rice dishes that are guaranteed to do the job (trust me).
It's generally busy in there and a little crowded, but certainly not uncomfortable. If you need a little more space and a less frenetic pace, try the location on Bloor. Basically the same menu and you can get a nice window table overlooking Bloor street. Very nice.
