the lunch menu has about 7-8 entrees on it and dinner has about 11-12 different things
they save 20% of the tables for same day reservations......so if you can't get what you want by calling in advance, just call the dining line that morning....
and when I made a ressie for 4th of July I found that they did release some tables about 3 weeks before the day....kinda like in waves.....
It depends on what season or day you are looking for....on usual days, I can make PSes a week in advance, but this week we're totally booked up....
