Just to continue to answer for others who might read this, it is very possible to be turned away. I have seen it happen in October. I have also seen 1.5 hour waits for a table and the bar was even full in October. So not a holiday. Both times may have just been flukes, but I wanted to say it DOES happen and not just on busy holidays. BTW, we had reservations and were seated on time (actually early).
