I ended up eating here several times on my trip.
The sign says they're open 23/7, and that seems accurate. I'm not sure what hour of the day they close, but whether I needed a late night bite or an early breakfast the doors were open and the kitchen was ready to go. The meatloaf is great and a veal chop they had on special one night was excellent. Breakfast wasn't always consistent, but overall I must have eaten here 7 times over the course of 2 weeks and I didn't get tired of the place.
