I saw this poster size menu in the Skipton Castle in the UK, and thought it was worth a mention. It was printed on foam board, gloss laminated, and then attached to a piece of white painted plywood on the wall.
While the gloss lamination makes the colors pop, we would never recommend it for something like this. As you can see, any lighting above the piece gives you reflection trouble, and can make it hard to read.
Matte lamination on this poster size menu would have been a much better choice. I would probably have suggested that we print it on Ultraboard without any lamination at all.
Other than that, it was a great looking large menu! As long as your prices don’t change a lot, this is a great way to give customers your list of goodies and the prices.
