Bottom line? Great for kids. Hell on earth for those without.
The prices weren't great - $6 for an ice cream sundae? - but the ice cream was good, and the options are many. They have a whole desserts-only menu, for Pete's sake.
The serving dishes are just small enough that if the ice cream melts at all, there's an overflow - but that's just incentive to eat faster, right?
I've never been when the place isn't packed, but with a real merry-go-round in use, it's not surprising.
