As not much details were provided in the description, my expectations were not high. But this turned out to be a really worthwhile tour!
For the workshop, we were provided with (already cooked) ingredients for chicken rice, and guided by an instructor to assemble the ingredients into a mini chicken rice cake of sorts. It was fun and no cooking knowledge was required - suitable for children and elderly! The instructor was friendly and clear with her instructions. And while we were not actually given the opportunity to cook chicken rice, one of the chefs came over and we could ask him questions on preparing chicken rice. Thereafter, we were served a sumptuous and delicious lunch.
As for the gardens by the bay part of the tour, there was no transport provided to gardens by the bay and this part seems a bit random actually, but it was nonetheless a nice bonus.
