The Unicorn is a great place to grab a bite on Stephen Ave.
Most recently I had a Reuben sandwich at the Unicorn and was impressed by the bread and the amount of meat I was served. I was also quite happy to see that the sandwich was also provided with a jar of hot mustard that could be added to the sandwich. I had the sandwich with fries and they were crisp and tasty as well.
The staff were all very nice and responsive even though it was a weekday lunch in down-town Calgary. The prices were definitely fair especially considering the location.
If you're there in the summer, be sure to grab a seat out on the patio before they all fill up!
