I have always been able to reach him at
Citydiner@live.com. I have heard a few complaints about the old location lately. I don't know if it has anything to do with the construction in the area or not, but that could attribute to the cleanliness of the space. Of course, his absence due to the new openings, would have an impact if his managers are inexperienced or negligent.
Hopefully, he can get this sorted out quickly.
