Mellow Mushroom is a southern pizza chain of about 150 stores, many of them franchised. We went to the one on Oleander in Wilmington on a Monday night to play PENGO, a variation of bingo put on by a local radio station for prizes such as concert tickets. Our kids go here often and it's fun.
There are quite a few pizza options, including build your own. You choose a size, the sauce, the toppings and it is priced accordingly, on Mondays they start at six bucks for the small. I was going to create my own when I saw, and ordered, a blue bayou pizza for fifteen bucks. It had shrimp, a blue cheese base, and andouille sausage. It was very good, surprisingly good in fact.
There is a good beer selection, we had the Highland Oatmeal Stout. The service is friendly, but a bit chaotic. The food is good, they even have an excellent gluten free option, and reasonable. The atmosphere is fun. I'd go back again. Oh, and we didn't win at PENGO.
