There is no priority seating and yes, seating is limited. To make matter worse, they have some tables for six that, no blame, a couple of two will take because no other option. If you sit at a specific counter, have to eat what they serve there.
Never saw anyone take food out but not sure if allowed or not.
I know some say portions large, not really, I'd call most a tasting. No trays so not sure how you would cart a bunch of food off. Are you in a Haven suite? If so, the Haven elevators are very close by but they for sure don't stop at 9. Other elevators forward of the Local so a hike.
A better option if weather is good is order at spot and take food outside weather permitted or, if they let you, grab food and eat at tables in Local which are right there.. Lots of seating outside.
