Hi I have a reservation for Cafeteria for 6 pm on a Monday night. All other slots are "booked" according to opentable. Just read that place is open 24/7 so am now confused. Is this the type of place you need a reservation for a later supper say 8 pm or do they only take reservations for peak supper times? Would love to go later since a 6 pm resetvation feels like its limiting my plans. Thanks!
