My friends are staying in Princeville in Kauai and at the Hilton in Kona for their honeymoon. I wanted to treat them to a really nice dinner near one of those locations for part of their wedding present. Any suggestions would be greatly appreciated! Also, when one does something like this, do you generally tell the restaurant a set amount on your credit card or do you give them your credit card number and leave the tab open? Thanks in advance!
