Definitely recommend renting a private karaoke room if you get the chance. It was the perfect birthday experience and my family and I had so much fun. The room was definitely pricey but in general, you aren't gallavanting around Scottsdale w/o money. They definitely don't exaggerate when they warn you the rooms are small, think large walk in closet size for the smaller rooms. My intimate party of 8 fit ok but definitely don't think a bunch of strangers would feel comfortable in this small room. The larger room can accommodate many more people and has the disco lights and stripper pole. The waitress to our room was very helpful and accommodating. It must be tought to work in such a high energy/fast paced/drunken/loud environment so definitely props to them. The machine worked fine and after a couple hours and one too many sake bombers, you're not even singing the same song on the screen anyway. The song selection was huge! Lots of fun and easy to use. I wish they would put two books in the rooms though so multiple people can look it over and pick songs simultaneously.
Food wise, my favorite were the short ribs. It came with our appetizer platter and we ended up ordering another plate of it. Possibly one of the most delicious things I have ever eaten. The edamame was really good too. Everyone in the party enjoyed the myriad of sushi they ordered although I myself am not a big sushi fan.
