I've only had their Vietnamese subs so I can only comment on that. Their subs are among the cheapest in town and if you order for take-out it comes with a free can of pop. $6 for a sub and pop is a great value (rare nowadays in Calgary).
Dining area is clean and staff/owners are friendly. Whenever I wait for my to-go order they offer me something to drink and allow me to sit down.
It would get 5-stars if the dining room decorations were a little less tacky.
