Mellow Mushroom has a definite funkified feel...just take a gander at the psychedelic 70's bus in the middle of the dining room. (The kiddos love eating in the bus from what I've seen.)
While I can't complain about anything, I can't rave either. The salad was typical salad, the meatballs were typical meatballs...and the pizza, well, it's good, but not the kind of pizza I like to go out for.
We had the mighty meaty and house special pizza, and it was LOADED with toppings and cheese. This is one dense, doughy pizza. If that's you're thing, then go for it. If you're like me and like a thin, crusty chewy Neapolitan style pie, this ain't gonna cut it.
Overall, I'd go for pizza and drinks on a casual night, but other than that...find me a good pizza joint where I won't feel greasy and bloated afterward!
