Review for Happy Half Hour Night experience: our group decided to take part in the happy half hour at the Groupon rate of $40/person rather than the standard ticket price $52.
The bartender was very lively and explained the rules for everyone to get their drinks. She also did a shot for everyone in the pod at the very top including a countdown. Overall the view was amazing and the drinks not bad at all. In the half hour round trip we managed 3 drinks and 3 shots at a comfortable pace.
Note: the wheel doesn't stop spinning, so you have to walk on and off the pod while it's moving. Even though it's moving very slowly, this maneuver definitely took more effort exiting after the drinks. Watch out!
