Question 1

How does 531 work?

Accepted Answer

Player one picks five cuisines, player two keeps three, player one picks one, and 531 commits you to a single restaurant nearby, drawn live from OpenStreetMap and Google.

Question 2

Is 531 free?

Accepted Answer

Yes, during the beta. You can play without an account.

Question 3

Which cities does 531 work in?

Accepted Answer

Any city. Lisbon was mapped first, with selection by its 24 districts.

Question 4

Does 531 store restaurant data?

Accepted Answer

No. Restaurant information is fetched live each time you play and is not stored by 531.

Question 5

My partner and I always argue about where to eat. What can we do?

Accepted Answer

Use a fair rule instead of a debate. In 531 one of you picks five cuisines, the other keeps three, the first picks one, and 531 names a restaurant nearby. Each person shapes the result, so nobody wins or loses the argument.

Question 6

What should we eat tonight?

Accepted Answer

Open 531.menu, enter your city and time, and play the three moves. You get one restaurant that is open then and fits your diet and budget.

Question 7

Is there an app that picks a restaurant for two people?

Accepted Answer

Yes. 531 runs in any browser at 531.menu, on one phone or on two linked phones. iPhone and Android apps are planned.
