I recently planned my birthday party here complete with trying the "MONSTER PIZZA CHALLENGE" I have to say from the time I called to ask about having my party there to the time we left that night the staff there was awesome! It's so rare to find genuinely friendly staff in Las Vegas. They had our reservation perfect and gave my party it's own side of the restaurant. There was games for the kids. The pizza was very good. Roberto is a great manager (owner?) and he accommodated us with every need we had, which included staying open a little late. Do yourself a favor and go and support a Las Vegas business that deserves your money, time and appetite.
ps - all you other Las Vegas business owners, Go to Graziano's Pizza and take note of how to treat customers right.
