OpenTable hints

• At the moment, there are 3 tables available every day: a table for 4 at 5:30pm, a table for 4 at 9:00pm, and a table for 2 at 9:00. On Friday, Saturday, and Sunday there are three lunch tables available also: a table for 2 at 11:00 am, one at 11:15am and a table for 4 at 11:00am. For Per Se, there's a nightly dinner table for 4 at 5:30. I haven't seen anything else available.
• The tables are "opened up" manually by someone at the restaurant between 10am and 11am Pacific time.
• Go to this page (French Laundry) or this page (Per Se) For the time, use 7:30 pm. OpenTable will look two hours before and two hours after for a suitable reservation, so this way you'll find both the 5:30 and the 9pm seatings.
• Realize that during some months it can be impossible to use OpenTable to book these reservations at all. Because of French Laundry's policy that reservations can be made only 2 months in advance, OpenTable limits tables on their site to 61 days out. This is correct in all months except for reservations in February and September, when the two preceeding months have 31 days each.

Good luck!
