Went for a friend's b-day.
I think they limit you to ONE liter mug fill on your special day (with ID).
Had the abbey dubbel which was SPECTACULAR!!
The fries were great as I remember -- it's been a while since I've been in. The pulled pork with beer cheese fries may need salt and pepper, it did for me.
PRO-TIP: The Frenched wings usually have a small bone in there, so don't go tearing into them, be careful! There's also the normal end cartilage.
PRO-TIP#2: Flights are $8 for 5 glasses. Great for sampling, sharing, and discussing with friends!
