I've been to mellow mushroom many times since it's been opened. They have unique pizzas, good beer selection and always busy on the weekends.
I just went last night since I recently went vegan due to health issues and heard they have vegan options. I thought I paid a lot already for a normal pizza but my goodness I paid way too much for 2 small pizzas and 2 beers.
I ordered vegan cheese, red sauce, caramelized onions and tempeh. It wasn't bad. Sauce was non existent though and they forgot the tempeh so I pretty much had a vegan cheese and onion pizza with the world's thinnest layer of sauce. Charged me for the tempeh which the waitress took off but even after that, my bill was $47 before tip! Seriously? I'll start making my own vegan pizzas and remember to add tempeh.
Oh btw, they charge premium for vegan options so remember that! I have purchased all those vegan ingredients at home separately and I don't understand how they can charge so much more. Needless to say, I'll save my $50+ for 2 pizzas and 2 beers and cook it at home.
