Kosmos is a wonderful place to grab some Greek-American food.
The Gyros are made well, using fresh ingredients. It can be a bit messy, so just ask that the sauce is either on the side or that they don't put too much on there.
The service is fast, but not so fast that the quality of food is compromised.
The location is great. Its near a small parking lot across the street and is walking distance from the University.
Food-wise, its ALWAYS tasty. If you get fries, make sure you order some tzaziki sauce for dipping. You'll love it! The Hummus is always warm and served with (you guessed it) warm pita bread!
I have converted many non-hummus eaters with this place. Now they can't get enough of it.
Also, for a sweet treat, order their sweet iced coffee. Its my favorite!
