If you do drop Y1000 on a dinner at Dadong, you can either use Wx/Ap and pay a small conversion fee on the difference between 200 and 1000 or pay directly with your credit card (minor risk of DCC). I suppose you could also break the 1000 into 5 separate payments; that's common with group dinners, but a little tacky if it's just you and your family members.
