This is my favorite place to be Friday and Saturday nights. I've been coming here since shortly after I moved to Vegas. I've stopped in during the day a few times, but I must agree with Dustin D - if you've not been here for karaoke, then you just haven't been.
First off - service is always great. The bartenders are friendly, get to know you if you show up regularly, and the servers are fast. The food itself is VERY good - their pizza is hot and very tasty, the sandwiches are delicious, and the pasta is fantastic.
On to the heart of the review - happy hour! They have great happy hour specials on drinks AND food. The garlic knots are the shiznaz! Friday night is ladies' night from 10pm to midnight and they do giveaways on Saturday night. TJ rocks the place with Karate Karaoke on the patio (weather permitting). They have heaters there if it gets chilly, so karaoke happens on the patio most weekends.
Simply put - if you've never been here or haven't been in a while, GO. If you're a karaoke nut like me, sign up with the dojo and get cool prizes while you're at it. You see a lot of the same people there on the weekends, so if you're looking to make some friends while you're having a good time (like I did) this is a great place to try it out.
