This place is what it is (an expression I loathe, yet it's so fitting in this case). Other Yelpers comment that Mardis Gras isn't sure what it wants to be. Maybe that's why I like it. It's not trying to be anything other than a place for people to come together and have a few drinks. The bartenders are nice and astute so they won't let you go thirsty. The owners are always there and they are real friendly and nice.
The food here is surprisingly good! You wouldn't think it but it's awesome. I'd even go out on a limb and say that the fries are better than McDonalds!
The place has a stage for live acts. My brother's band has played here with no problems and the sound system was awesome. Comedians come through here, too. There is a pool table, beer pong table, darts, Golden Tee, etc. There are TV's to catch the game.
Karaoke nights are great here as well. There's always a good mixture of people and nobody cares what kind of song you do. The KJ Shawn has a great selection of songs.
If you're in the area stop on by. Come witness the un-snooty side of Scottsdale.
