My husband and I did the booze, bites, and brothels tour a couple of weeks ago. It was not the best food tour I have been on. From the start, everything was late. We called multiple times, but got no answer, and our guide showed up 5 minutes late. We then had to wait ~10 minutes for everyone else to get there, since some people had come and left by the time she was there.
She started out very rude, she blamed several people on the tour for delaying us for not putting in that there were restrictions to what they could eat. Then we get to the first place, and did not get served for a LOONG time. She actually got into an argument with someone at the restaurant about how long it was taking, and eventually several people were served, but the last plate was put down just as we got our "3 minutes to finish warning." --very disorganized.
We went to several places, none of the food or drinks were great. I would not go back to any of the restaurants. Usually we do food tours to try the authentic or hidden gem food places.... these places were just.... well neither of those things.
Our tour guides mood did get better as the tour went on, but she didn't talk a ton about much of anything. It just seemed really disorganized. I would not recommend anyone waste their time. I did however hear that there is a little Italy food tour that was good, so maybe go try that one...
