Cheeburger, Cheeburger makes a big production out of its milk shakes. There are something like 75 flavors of ice cream, and every milk shake comes with two straws and a spoon. Get the large size and ask for the double chocolate flavor — malted. Then be prepared to have your milk shake stolen by the rest of your dining companions. If you remember chocolate malts, this one will make tears of nostalgia well up in your eyes. If you have never tried one, you are in for a treat. Cheeburger, Cheeburger takes its name from the Saturday Night Live routine. "They said 'No Coke, Pepsi' all the time, and that's why we have no Coke, only Pepsi products," the teen-age waiters chirp with big phony smiles. Located in the Vintage Park Shopping Center at the Louetta exit off Highway 249, this outpost of a Florida-based gourmet hamburger franchise is decorated in pink neon and stainless steel to mimic a vintage neighborhood joint of the 1950s. John Belushi would have hated the place.
