In all my four years in college in Orlando, I never visited the Mellow Mushroom in Winter Park. Then I go home to Jax for a weekend and went to the brand new one built near my house on 3 of the 4 days I was there. (Mostly because my friend-I-made-the-drive-to-visit's girlfriend du jour works there.) I was kicking myself for not trying it until then. It was frickin' awesome and had the best, most dense meat lover pizza I've tried so far. The crust was actually delicious and far from just an afterthought. I remember the prices being only moderately "upscale," but thankfully my friend spent his per-diem buying all his friends lunch/dinner/drinks the whole time. (Ironically becoming the only heavy boozing I've done and at the end of my college career.) It's not an in-and-out pizza place. They're a pizza/subs/pita/salad/bar restaurant. If you're a beer fan, they've got a list you can drink through to get yourself a t-shirt.
As for CiCi's, it's true it's become totally disgusting over the years, but I always have fond memories of going there in high school for stuff-your-face eating contest with my friends and playing outdated arcade games. Every so often I stop at one still and happily pay the price just to gorge myself on the cheesy bread. (Yeah, yeah, sue me; I'm not really a cinnamon roll fan of any sort.)
Also, though the actual pizza is average, I'm a big fan of Hungry Howie's flavor crusts. mm, spicy!
