Wonderful. Loved the atmosphere, price and food at Zaks. I was in town for a conference and everyone was raving about it. There was so much food. Classic.

Was here a few years ago. It is still a diner. Food was just ok. Lots of loud teens in the place when we were there. There are lots of better places to eat in Ottawa.
