I visited Babylon several times while visiting Calgary, and my feelings on it have ranged between decently good to really good.
On a few visits, a couple of elementary school aged kids were the ones assembling my order. It's nice to see them getting in on the family business, but they should be more supervised for better quality control. They couldn't seem to get my kibby hot. The adults who work there have a better command of microwave use.
What keeps me coming back is the chicken shawarma. Whether wrapped in pita, topping a salad, or as a part of the platter, it is very tasty -- especially topped with tahini and hot sauces!
I wouldn't go out of your way to try this place, but if you're in Eau Claire and hungry, it's certainly a worthy option.
