I made a reservation at the Cafe as we have not been to San Giorgio in our many visits to Venice.
I cannot seem to locate a menu. Their website is not much help and only lists beverages. Has anyone eaten
there and if so, any help as to what type of fare they have would be helpful.
This might help, gives a general idea. Light meals, by the look of it.

It looks like it's an expensive 'tapa bar' like place. You go there for drinks and some fancily presented small food plate to go with it. It's probably a nice place to sit and enjoy the view at NYC or SF prices.
