I was pedaling away on an exercise bike Wednesday at USA Gym when a Channel 4 News restaurant report appeared on TV. The report said 90 new restaurants opened inside Nashville city limits in 2016, with an estimated 115 new restaurants projected to open this year.Those are eye-popping numbers when you consider those are just new restaurants. Think about how many are already operational. It makes you wonder how many restaurants one city can support, even a very large one.The problem, according to the news report, is the restaurants are struggling to find workers.
