They'll make you what you want at any time
We did not have lunch, but have driven by at that time and there were cars in the parking lot. May be presumptious, but i would think you could get lunch then.
I think they start lunch at 10:30 or 11:00 a.m.
I've had hikers get the holy cow burger at 10am before
Although it isn't mentioned anywhere on their website I am sure you can expect to be able to order lunch around 11:30 or later
