Cedar Hill Dairy Joy (in Weston) is a roadside drive-up (window service) ice cream shop that also does hotdogs and hamburgers. Good soft-serve dip cones too. Popular spot for convertibles and other shiny cars; has two outdoor patios and picnic benches under the nearby trees.
If you're picking something up for me: that probably won't work because what I always get from here is a vanilla soft-serve cone dipped in chocolate (medium-sized, it is impossible to finish a large without wearing most of it and even a medium is pushing it) and dip cones are basically untransportable.
