First time back to the theater since the pandemic. I’d like to eat at Beco after the theater but the hours posted only go until 10 PM. Is it still possible to eat here after a show?

Becco caters to the before/after matinee and the before evening show crowd. Reservations can be made on Open Table for beginning at 12 noon and ending at 10 pm. IMO the show you are attending would need to be done by 9:40 at the latest for you to have a shot at making it to Becco by 10. I recommend trying the make reservations before the show.

I have no idea when the restaurant closes. I suggest calling and see if they have seating after 10 pm
