Chicago's fabulous Diner Grill (which scores an 8 on the Diner Project Scale) also seems to go by the name Dinner Grill.

This was one of the best diner experiences I've had in some time. When Dave and I visited in April we went at regular dinner time. The diner conversation about a El accident was inspired by the tv. Somehow the talk led to the new tv converter boxes (time will tell is one replaces the tape, wires and bunny ears at the Diner Grill). There seemed to be a consensus at the diner to wait to buy boxes (government coupons deemed overrated) until they're cheap and on the street. (They're probably right- I got the coupon and I still had to pay $20). The best part of this visit was the man who came in after work, sat down, no words exchanged. He received his chili and a specific number of crackers within minutes. Yummy Grilled Cheese (of course).
