Always busy here.... Super busy on the weekends. Bring patience with you :) Currently there are 21 people who have ordered, paid and are standing around waiting on food. There is no "waiting area" so you'll be in front of the coffee, the soft drink machine and halfway down the hall to the toilet :)
From the time I paid for my food (two bagels, toasted with cream cheese) it was 16 minutes until they put it in my hand.
