We went to Jaxson's, which has been voted the best ice cream in the Miami area. We got a ginormous hot fudge banana split. It came with 3 grapefruit sized scoops of homemade ice cream, hot fudge, and whipped cream. Also there were some bananas in there. So it is healthy (just kidding). All for $8.25. They have something called the kitchen sink (minimum four people) that actually comes in a sink and has three scoops of ice cream per person.
If you're ever here, the best burgers in South Florida are in Ft. Lauderdale.
