Pannizza is just down the street from where I live, so I've been there a good number of times. It opened not so long ago, but it already seems to be doing really well. The owner, Eric, is an extremely nice guy, and the staff in general are very friendly. The service is very good, the food is ready quite quick (2:15 minutes to be exact, as is their slogan).
The menu at Pannizza is pretty extensive. There is a set menu, and it's also possible to build your own pizza/pannini. There are a lot of options in terms of the meats/vegetables you can put on the pizza, and the staff are more than willing to help with the selection process. The great thing is, there's no added cost for making your own, and you can put as many toppings as your stomach desires. It's not an expensive place - about $10 for a pizza and $7 for a panini.
The first time I went, I tried the Med pizza (pesto sauce, seasoned chicken and a bunch of vegetables). The pesto sauce was a pleasant inclusion on the pizza. I've never tried pesto on a pizza before, and I have to say, it's really worth it. Other times I've made my own pizzas or had the Nonna (meatballs).
I've tried the Panini once, and it was toasted to perfection. The only issue I had with it was that it wasn't filling enough :( The dessert pizzas aren't bad either, but they can be a bit too sweet (or maybe it's just me!).
I'm definitely going to keep going back to Pannizza as long as I live in the area. It's a great place to swing by if I want to grab a quick meal, and it's even good to sit down with friends over a scrumptious lunch.
