We visited Pepper Market twice on our trip 2 weeks ago and used vouchers. Sharing is not a problem. The server will seat you and leave you with a card to be stamped by the different food stations you visit. You "pay" on your way out by giving the cashier your stamped card and your voucher (s)
My DH says this is his new favorite place to eat as the Grill had ribeye steak and potato and grilled veggies grilled to order.
As a matter of fact, we had 3 children and used 1 voucher to get the chinese noodles and bourbon chicken and that was plenty for them.
