I think this topic is broad enough to be posted in this forum. I'm going to be visiting these countries next month. Does anyone here have any tips or information on where to get cheap food in Amsterdam, Cologne, Brussels, Brugges, Ghent, Milan, Venice, Bologna, Florence, and Rome? I know it's a long list, but it would be nice to have a list of tips on where to go and get cheap food along with which supermarket to go to stockup on drinks to put in the hotel room.

Thanks!
