Cleveland's got a ton of great pizza places, and this is at the top of the list. It's the best pizza place on the West Side--nothing comes close.
I've been here twice--one for a large birthday gathering and once for Mother's Day. I've gotten outstanding service both times. On Mother's Day, our server disappeared for a long period of time for some reason and I was pretty bummed. However, she made up for it by apologizing sincerely and profusely and making our drinks free! That's outstanding service right there--some other places make you feel like they're doing you a favor by allowing you to eat there, rather than making you feel like you're the guest and they want to make you feel good about eating there.
The pizza is amazing and you can get it as simple or complex as you want it. The Mac and Cheese pizza and the Acapulco BBQ are especially good! The fact that they offer a deep dish option for no additional charge is especially awesome--some other places would probably add an additional charge!
My only beef is that the prices are a teeny, teeny bit high and the pieces can be a tad small. Don't let it deter you from going there unless eating there will send you into bankruptcy--it's the best pizza place on the West Side, hands down--but if Pizza BoGo on the East Side was located right next to it, I'd probably pick BoGo a bit more often. (Edit: I was told like 5 minutes after writing this review that it is half off on Monday's for dining in, so go there on Mondays!) Having said that, I am always very excited for a trip to Angelo's!
