I did it years ago on Ecstasy and liked it. To me, the galley tour is an integral part of the experience and I would not do it without that portion. They stopped the galley tour due to COVID and IDK if they've reintroduced it.
Even with the galley tour, my wife and I enjoyed Chef's Table on Ecstasy but neither of us really have a desire to do it again. I have heard from others that do it every cruise. Each to their own!
