It occurs to me that a problem that is particularly serious in Paris is that of diners' reserving a panoply of tables so that they can decide at the last moment which one strikes their fancy and mood. As a forum, where we counsel on methods of securing reservations, menu translations, even proper dress attire, we have been derelict in not warning visitors against this quite unacceptable practice.
When just one person double books, he is keeping another from securing a table. Worse, he is stealing from the restaurant by keeping them from selling a table until the last minute if at all. Of course, this assumes that he has the presence to call and cancel the reservation he does not keep.
Visitors need to do homework, like the scores who visit Chowhound every day, and decide their preferences before they book. Then, book the one table that sings to their hearts. Booking two tables will not increase one's odds of having a memorable meal. It only decreases other diners' chances of doing the same.
Come to Chowhound and pound us with questions. We are all here to answer questions in infinite detail. Just ask. Then choose your table and enjoy!
