Tang is... ok. It reminded me a lot of a Thai Tai. Except more normalized for the burbs. Normalized meaning less options. Basically, a few smoothies, a few Vietnamese subs, some vermicelli bowls, etc.
Service and process gets 4 stars. The girls working the cash and prepping the smoothies were fast and efficient at noon hour on a Saturday. And the folks in the back were prompt with getting those subs out and ready to eat.
I wouldn't make the trip all the way out to Deerfoot Meadows to hit up Tang, but I'd certainly pick it over some other options in the area.
