I've had the pleasure of dining at Pizza Rock quite a few times and for the most part they are pretty good. They are a bit on the pricey side and service can be spotty, but the food is always on point and delivered hot and fresh to your table. The interior is pretty cool, it is large and open, there is even a semi-truck on the inside!
I'm a big fan of the Old Chicago pizza, the meatballs are delicious and the fresh ricotta is creamy and melts in your mouth. The Cal-Italia is an interesting choice if you are in the mood for something a bit sweet. All of the ingredients work really well together, despite sounding a bit odd. I've also tried the Burrata burger and while it was a good burger I think that Burrata is too delicate to melt on a burger. It's a cheese that you need to eat alone to really appreciate the flavor. I've also had their meatball sub and while I wasn't a huge fan of the bun, the meatballs were flavorful and delicious. The rosemary and sea salt garlic fries are a pretty good side as well.
They also have a counter right inside the door where you can grab a quick slice. I've spent many lunch breaks perched at the counter with a slice. Again, it's a bit pricey, but the slices are huge and you can try a variety of toppings.
I think that Pizza Rock is a great addition to downtown. It's great for big groups and it's nice to have an artisan pizza restaurant within walking distance from work.
