A regular staple for hundreds of Calgarian everyday who need to buy lunch, Sunterra has been successfully satisfying its customers for years. This is an excellent option is you are look for quick food that is a slight step up from cafeteria options in Banker's Hall.
There are many health conscious options inside. Their baguettes are a nice grab and go option. Not to mention their desserts rarely disappoint.
However as an individual who adheres to a primal/paleo diet, the salad bar is my oasis from a bread and cheese obsessed world (not that there is anything wrong with that). The options are immense from spinach to tuna to chicken to olives to eggs to dried cranberries to seeds. Just pick and choose and you are ready to go, so simple an Arc can handle it. There is even oil and balsamic vinegar available at hand if you are not interested is the dressing options at the bar.
I forget the actual cost as they charge by weight,$1.69 per 100g. I usually pay around $8 for a very satisfying size of salad. This is reasonable price compared to other options nearby.
A wonderful down-town option for all you primals/paleos out there.
