I can’t help but feel sorry for independent restaurant owners who can’t depend on their service staff when they are out of the restaurant. Therefore, it is with a heavy heart that I write about my recent visit to Nosh. When owners Celeste and Avner Samuel are in the house, the service sings smoothly. On a Wednesday evening at 6:45 pm, they were not present. The scene I witnessed was like an episode of Restaurant Stakeout, the TV show that installs hidden cameras and lets the owners watch the horror shows that take place in their absence.
