I was there around 2pm today. Quite manageable. I actually got more of my Pesach shopping done than I expected to.
Some items had misleading or missing prices (clear plastic plates and bowls had a price which I understood to be a case price, but was actually a unit price). Plastic bowls and plates by the case Bingo brand (as opposed to BluShine or Basix brands which are sold in bags of 125) didn't have a price listed.
I liked finding oil under supervision of בד״ץ עדה החרדית ירושלים.
When I was mostly done, I had my son wait on line, while I got some small items here and there. Overall was quite an efficient shopping experience. They didn't have EVERYTHING I would buy for Pesach. But definitely saved me trips (and probably money).
