This Malley's is quite awesome. Everyone's dressed kind of like they're in the 1950s. In fact, going in looks just like the opening to the film I linked to above (we don't need no Tim Burton for this).
It doesn't stop there. There's a moving carousel, complete with chairs and tables so you can sit down and twirl around at a slow pace while eating ice cream or chocolate or other wonderful things.
Now, the food: I got a hot fudge sundae, but they also had other awesome options, including peanut butter options or ones that looked like various animals and clowns. The hot fudge sundae was excellent: the ice cream was very good, and the fudge was also excellent :)
They also have lots of candy. Basically, it's a wonderful place.
And for the heck of it, here's the other song from the movie, because I can http://www.youtube.com/watch?v=29_uSlEEPSk Go listen to this while you read reviews about Wall Street or something.
