Fodor's Expert Review Graceway Gourmet
The Grace Bay branch of Provo's largest supermarket is likely to have what you're looking for, including a selection of nice wines and beers. Walkable from many of the resorts, it's especially popular for its prepared foods, which can be taken back and quickly reheated in your condo's kitchen when you don't feel like cooking from scratch or heading out to eat. You will also find it's a good stop for inexpensive beach toys; there's a separate little shop for them just inside the door.
