Even more succinctly: establishing consensus should be fun in and of itself. People dont know what they dont know. They dont want to plan. They do want to daydream.

Make voting addictive and make the tally results easy to interpret, and aggregated. Not only what restaurants got picked, but a sum of them by type. Popeyes may have gotten 3 votes, but "Mexican Cantinas" may have gotten 4, albeit 4 different restaurants.

Things like "what cities I want to visit with my friends" may or may not change between years.
