If you've read any of these reviews, I'm sure you see the recurring theme- you come here for the experience...certainly not for the food or service.
One star for the organ- it's truly a thing of beauty. You should wander upstairs while you're there so you can get the full effect. The second star is for the the people who play the organ. They are EXTREMELY talented. When I watch them play, I'm totally in awe.
Sadly, two stars is the highest I can rate Organ Stop. This is a great place to take out of town guests, kids, or winter visitors. Just don't expect to be wow'ed by anything other than the music. Pizza is not so great, service is just ok, and cash only? Seriously? Plus the way you order is a mess. I wish Organ Stop would make a few updates to make the experience better but since they can make loads of money without changing a thing, I won't hold my breath.
