How difficult is it to get seating on a Friday evening--assuming the weather is nice outside? Do they take reservations for seating?

No reservations for seating. 1st come 1st serve. Crazy busy on the weekends especially at night.

Also it's more like a food court, it's good food but it doesn't work like your typical restaurant

It's a pretty big place with tons of seating.

No reservations. Evenings and weekends are always busy. Be patient. It's worth the wait.
