Mac's is in Clifton Heights, and when David and lived on Flora Street in college, we'd walk up there or to King Wok often.
Mac's has very good loaded fries (waffle style), with two types of cheese and bacon. I was obsessed with them for an entire quarter. They have very good chicken fingers too. They also have very good pizzas, including a vegan one for all the college vegan hipsters.
They have a few interesting beers on tap, including local Mt. Carmel Brewery. They also do Karaoke some nights.
All their prices are very reasonable--their clientele is mainly college kids, so that's a plus.
