I was pleasantly surprised by Cafe Koi. I went here because I wanted to go to a vegetarian friendly place that was near the Telus Convention Center. They accommodated my sister and I despite the fact that they were about to host an event and my sister arrived late. They were really friendly, and the food that we got was SOOOO good! My sister got the Buddha burger, and I got the Lotus bowl. When we were looking over the menu my sister asked me if I minded her getting a burger, and I said no. Then I noticed she ordered the Buddha burger, and I decided to refrain from pointing out that she order a vegan black bean burger! She LOVED it! I loved the Lotus bowl too! The sauce was worth the award it has won in the past! They also take $2 off of vegetarian meals on Monday nights which was an added bonus.
I also think it is great that the support the local community music scene and have a couple of open mic nights a week.
I definitely recommend checking this place out if you are in downtown Calgary!
