I went with a large group (17 of us) and I was expecting a headache to say the least, never mind the fact that we went on a Friday night.
Our table was ready at the time we had reserved and our waitress was top notch. She did not miss a beat at all through out the night. We were all truly impressed.
The food was pretty good as well, I do not think anyone had any complaints there.
If you are looking for a sports bar type place (also has a mini-stage for music) and decent food with great service, definitely give JJ's a try.
