From the above post: http://www.bigdaddys.ca (note: there are 2 Ottawa locations... the one on Elgin can be a bit of a party atmosphere as its on the main drag - but then again it might get you into the spirit of the experience?
Theres also Fat Tuesdays in the Byward. Been there once but only for drinks and apps. The overall experince was positive and had a good time. The courtyard out back reminds me a bit of Pat O's in NOLA. I think thats what they were going for as the dualing pianos remind me of there too. I think its worth a try.
