Some Pocket Concierge restaurants let you join a waitlist on their page. Their help site is currently unreachable, so follow what the restaurant's own page shows.

We still send you release-date alerts: for a set release date, the day before, on the morning of release day (08:00 JST) and about 30 minutes before when the time is known; for houses that open a little every day, a weekly summary.
