Disclosure Rounds

Participate in three rounds of group decision-making. In each round, you'll select your restaurant preferences based on certain attributes. The group advances to the next round once all members have submitted their choices for the current round. Email notifications will be sent when it's your turn to make a selection. The duration of this phase is heavily dependent on your group's pace and response time.
