We only did the tour (not a luncheon or dinner one). Food and drinks are available for purchase during the regular tours though for additional cost.

The tour was very informative. My friend and I had trouble hearing the early part because many people near us were carrying on their own loud conversations. I kind of wish they'd had sections for those wanting to pay attention to the tour spiel and those who just wanted to socialize with friends.

It was interesting to see the various bridges and how they operated. We got to see a train use one of the bridges both on our way out and on our way back.
