This is definitely the place to go if you are a vegan who misses Mac and Cheese. Every so often I get a craving for it and hit up Cheeseology. It is also a great place to take non-vegans.
You can make your own dish by picking your cheese (or vegan cheese) and veggies, or have one of the standard dishes made vegan. I always get the Mediterranean Mac and Cheese w/Daiya, which includes olives, artichokes, and sun-dried tomatoes, and it's awesome.
I don't particularly recommend the bread sticks with marinara as I have not been impressed (and the sauce is served cold), but the Mac and Cheese is delicious. For me, a small skillet is plenty.
Cons: Limited sides to eat with the pasta
