The menu posted by Gomac is for F. If you’re in F, you can dine when you please, though I would advise telling the CC what you would like when they first come to take orders, so it can be kept for you. You can either tell them when you’d like to eat, or just tell them that you’ll give them 30-40 mins notice when you’re ready. Of course, if you want to avail of the second meal too, I guess you wouldn’t wait too long for lunch.
