great!. classic 50's has been around for a while, and is a local institution. thefoodis better than sonic's, plus it has the whole "local" thing going for it (i guess in oklahoma sonic is local, but you know what i mean). the slushes are great, and they have quite a few flavors to choose from. the friend pickles are awesome. the best part, though, is that they make their own root beer and it's some of the best! price wise, it's about the same as other drive-ins. if you're in norman, it is worth checking out.
