Quoted from jackal2001:
I would expect it to be packed on a Fri-Sat night.
I hadn't been there on a weekend night either and when I went by the other night I noticed they were pretty busy. So I was thinking about maybe another place. There is Stooges which is a bar. I have heard the food is decent and its within walking distance. Still gets busy on weekends but not as much as Tilted Kilt.
