The cool thing about both courses is that they are completely and totally different, right down to the music. For my birthday my wife decided to get me completely obliterated at Pat O Brien's and after about 4 hurricanes, and two drinks from Fat Tuesdays she decided I was ready for the Horror side of minigolf. The down side was that it's right next to the valet parking, so in my drunken state I was slicing balls pretty hard at the people waiting, and apparently out onto Universal blvd. I don't remember much except for the aftermath....it was a good birthday.
Now before everyone goes "OMG ITS SO TERRIBLE! DRINKING! NOOO!" It was about 11:30 on a Saturday night, and naturally the spill over from Citywalk can play mini golf.
It's an amazing fun course, though a bit on the pricey side. Still, the final hole on both courses are amazing.
