Mac's pizza was good, but rest wasn't great. Took bartender/server to come over and take my order. The ice tea was nasty. The place was old and dirty. If you want great pizza and good service, go to Adriatico's Pizza about 2 blocks away. I won't be going back to Mac's again.
Mac's is one of my favorite places in Clifton. My college roommate and I like to visit when the students are gone between semesters to avoid students and the crowds. It's also easier to park when students are gone and it's one of the few restaurants in Clifton with a parking lot that's free. They're well known for their Friday pizza buffets, but they have loaded tater tots and they are the best. If Clifton is hard to get to, they also have other locations in town. The loaded tots alone are worth the trip.
