I have mixed feelings about this place -- not sure it lives up to the hype.
First, the atmosphere is very girly. I think it is supposed to look a little like a soda fountain, but there is a little too much pink and "Hello Kitty" stuff.
The prices are Las Vegas crazy -- like $17 for a hot dog or $12-15 for an ice cream sundae. I have eaten dinner there before, but its really not worth the prices that you pay.
The desserts, however, are quite good -- although still overpriced. The sundaes are really the draw for this place, with lots of interesting choices.
If you really like ice cream, give this place a try -- but expect to drop some cash.
