Mythos just seems heavy for "lunch" food.

I do want to go there, though. The July calendar has both parks open every Mon & Tues until 10 PM, so maybe Mythos will be open late enough to do an early dinner. We shall see!
I was JUST looking at the Margaritaville menu!

We will have dinner at US Monday & Tuesday, I just need to decide which restaurant on which day. I would imagine we'll have a break during the day Monday, so maybe eat at Margaritaville on our way back out Monday PM. Then go to IOA Tuesday and hit Mythos at whatever time we can. There won't be a break on Tuesday so a late lunch or early dinner might be good.
Any hints on dining reservations? When should I call?
