We used to order about six pizzas a month from this place, but are now done with Gennaro's. Last night, we ordered two LARGE (16"/12-cut) one-topping pizzas, but when the pizzas arrived, they were MEDIUM/14" size, with one cut into 10 slices and the other in eight. We checked the receipt to confirmed we were charged for LARGE pizzas and then called to let them know that they sent two mediums. The unapologetic response we got was that they've recently changed sizes and MEDIUM is the new LARGE. (You'd think they might have mentioned that to a regular customer?) So we ended up with the equivalent of 16 slices when we ordered 24.
Either somebody screwed up and they lied instead of fixing the problem OR they really are now charging large prices for medium pizzas. So I called the following day and asked to speak to the owner. The man who answered the phone said the owner wasn't available, but identified himself as the manager and confirmed the story. I pointed out to him that the menu on their website still shows that a large pizza is 16"/12-cut and he told me the website hadn't been updated yet.
There are lots of places to order pizza from on the South Side and I'm sure I can find another that's more worthy of my business than Gennaro's.
