I would pay X for an app that could maximize the happiness of deciding where to go eat...say I have a list of 3 choices, they have a list of 3 choices, we don't know each other's 1st choice or any choice for that matter, just that there was an agreement, and we're both satisfied.

We built an internal app similar to this at a previous workplace. It was a small company and most people would go out to lunch together every day. Getting everyone to agree where to go was the hardest part. The app would email everyone in the office at 11am so they could opt-in or opt-out that day. Based on who was going, the app would recommend 3 restaurants from Yelp and put them up for a vote. Voting would be open for an hour and ultimately we would go to lunch at the restaurant with the most votes. We trained it to be "smart" about its recommendations, taking into consideration who was going to lunch and their previous voting history. Neat idea, and it probably could have been generalized to work for happy hour, date night, or other group events.

Pick two and flip a coin.

When the coin is in the air, you will know which option you really want. Or you will go with what the coin has chosen, absolving you of the consequences of making the choice. "this restaurant sucked" "dont blame me, the coin picked it"

The OP seems to be talking about when two people are trying to settle this question and may have different priorities.

Wouldn't the coin flip still apply to that situation? He is asking for "something" else to make the decision. Coin\App\Dart throw\etc all work

I don't believe that fulfills the conditions described, no.
