I am fan of Atomic fo sho; it's my favourite Vietnamese sub spot in Calgary.
My favourite is the veggie sub with extra cilantro, though I've had the wasabi tuna sub and the sweet chicken one as well & both were very good. My husband loves the beef satay sub and - wait for it - the vegetarian sub! He's no vegetarian, so this is shocking news.
I often crave Atomic for lunch & am grateful to be within walking distance from work. Yum yum, subs in my tum!
