The reviews are pretty harsh and some very exaggerated. UT is not known for good clubs, at least dance clubs. Most of the clubs in SLC are full of trash, staff and bouncers are a bunch of idiots. We love to party and dance, Harryos is by far the best place in UT to do so. I have never been treated poorly at the door. Don't be a punk and they will treat you just fine. Don't expect them to be your best friend. These guys deal with a lot of idiots during the night. So forgive them if they check you ID and send you on your way.
Moving to the bartenders. I have only had one treat me poorly but I don't think he is there anymore. They are quick with the drinks. Like normal park city prices are higher then in SLC. Usually 5 tall drinks with Belvedere vodka and side car run about $55. (Yes, they still do sidecars but more in a side drink style. Same price though).
The sound system is awesome DJ Brisk on Sat nights really gets that place going. The dance floor IS NOT all VIP. A portion of it is but still plenty of room to dance and have a good time. Pretty big place but its true unless VIP nowhere to sit. This being the nature of most clubs this style. In Vegas not VIP, nowhere to sit. Manhattan, LA, Miami, same story. You want to sit and talk go to a lounge.
As far as the crowd goes, over the winter its a different crowd every night. You'll have your usual locals, but there are so many people in town skiing. You want to dance and unwind after a day on the slopes go to Harryos. Over the summer its a different story. Fri nights are usually dead, but they get some great headliners in on Fridays. Don't expect them to come on stage until at least 11:30. Sat nights are usually the night to go over the summer.
VIP service is reasonable for Utah. Worth it if you want to be treated like a king for the night.
Harryos is full of beautiful people and great music. Worth the drive up from SLC, Prov, or Ogd. If you're in town and want to meet people. Check it out most def.
