I eat here ALL the time. I work right nearby, so it's a perfect lunch spot. They have all the greasy diner requisites (grilled cheese, homeburger, french fries, onion rings), but also a great Greek Salad with Chicken, and a Chicken wrap with peppers and mushrooms that's really good.
Once you get past the smokers and people asking for money out front, you'll find some friendly staff and great, cheap food!
