Update: went to Nkrth Brunswick NJ location last night for dinner. 7:30PM. When I got there line was halfway to the door. By the time I sat down to eat it was not only to the door but past it. A constant influx of patrons flowed in keeping the line to the door during my 15 minutes there. This was another location a few months ago that was almost empty at this time.
This is now two data points for me personally witnessing. I now have a much higher level of confidence people are indeed returning and dramatically so in the last month.
