I am not much of a drinker but decided to try this place out after seeing people with their huge tumblers walking down the strip. I ended up getting the small mug ($10, $8 for refill) with a bellini dacquiri, which tastes strongly of peach schnapps with minimal alcohol. At first I thought I had been given a virgin drink but I did eventually get a slight buzz so I was okay with that.
Worth a visit.
