Tried them out at their new location at Fairmount and Franklin, and they produced a very good bahn mi at a pretty-good-by-Calgary-standards price.
(I'm accustomed to paying less than half that - $4.00 - for similar quality in Toronto's Chinatown.)
But Subs 'n' Bubbles is much better than most of the competition in Calgary. No sickly-sweet Thai chili sauce ruining the flavours, nice Bulgogi pork available, and a decent touch-of-fire from just the right amount of thinly-sliced jalapenos.
