...but IMO not suitable for vegans.
There might be a dry no-sauce no-cheese version for the vegan, but I'd recommend skipping this if you're vegan and checking out one of the other vegan spots in the area, as there are a bunch.
For the vegetarian though, I recommend it. This is a burger place with great burgers, served with your choice of fries, potato wedges, bulgur salad or just a salad with lettuce/cucumber/tomatoes. Lots of innovative burgers, like a Russian burger with horseradish and beets and an Elvis burger with peanut-butter (you want to ask them to exclude the bacon though). Also milkshakes and donuts.
Very good prices around lunchtime (11-3pm).Pros: Great burgerplace
Cons: Not for vegans
