First, a quick story. I was spending time with a friend a couple weeks ago, and we weren’t sure what to do for dinner. After a couple fruitless minutes on Yelp, I suggested sushi, my friend replied, “sure,” and we started walking to a nearby restaurant which we had both already been to.

The second we arrived, I realized my friend doesn’t eat seafood. I should have remembered this important detail, but I didn’t. My friend could have nixed my suggestion, but she didn’t want to seem finicky.

She insisted that we eat there, and we had a fine meal. It wasn’t the end of the world, but it was dissatisfying to know that we could have gone to a restaurant that would have suited our tastes better.

Since Facebook knows both our preferences, Events can suggest restaurants we would both love and haven’t tried before. In the example pictured above, Facebook detects our overlapping fondness for New American food and provides options within both of our budgets.
