I'm not exactly sure how old this place is, but I remember when it opened. To be honest, I never visited the place until my sister told me I *had* to go.
Good Golly Miss Molly this stuff rocks!
You can sample all of the daily flavours and for about $2 enjoy your own "kiddie" size (they're quite big) serving.
They also serve Nathan's hot dogs, so you can grab a quick easy lunch and dessert and enjoy it in a cool atmosphere -- it's a jungle/island theme.
They also have a punch card -- after 10 purchases, you get a free pint (I think it's a pint, anyway). I love punch cards....
