At the Plaza Restaurant in MK, they have great ice cream! I usually get a big scoop of mint chocolate chip with hot fudge! Mmm!
Ghirardelli has amazing sundaes. This is especially tasty for chocoholics like myself!
Garden Grill used to have great apple sizzler, lemon bar type pie, and strawberry shortcake. However, I'm not sure what they have there anymore since they've changed menus a few times.
Sci Fi has some really great desserts and their shakes are fantastic!
I know, you just wanted one, but I can't pick!
