We knew this was going to be an adventure ....
We had to travel from Frederick to Cleveland to see my father in the hospital, so we figured we'd break the long drive home with a quick detour into Pittsburgh for dinner ... preferably the best pizza they had to offer. Internet research indicated Murray Ave (Squirrel Hill) is the hotspot - and it's an easy exit right off an interstate. So why not? Of course, we happened to pick the one weekend where they closed Squirrel Hill tunnel on I-376 and sent traffic through a winding maze of city streets - which meant we spent an extra hour in stop/go traffic getting to Murray St, and then an extra 2 hours in even worse conditions getting back out onto the interstate.
Once we parked in an official spot near the restaurant - as opposed to the virtual parking spot the detour had become - we chose Aiellos; it had fewer reviews than Mineos, but all positive (seemed people either loved or hated Mineos).
Hard to believe - but the pizza was actually worth it all. It was that good. Crust just perfectly crisp and yet slightly chewy. Flavorful, lightly sweet sauce. Cheese perfectly browned (not soggy and underdone like so many pizza shops near our home). Friendly staff (I tried to pay, and the younger guy at the counter said "pay when you're done, if you don't like, don't pay at all").
We had a plain cheese pizza (the true test), and another with sausage, roasted peppers, onions. Both were excellent.
Take cash - they don't take cards (but do have an ATM). Don't expect ambience - there's maybe half dozen hard booths and plastic utensils. No beer or wine ... though I think I read somewhere that you can bring your own (? - call them first). This is a low key affair, but the pizza really is as good as everyone else is saying ...
