That grocery store is called Goodings.
If you take Hotel Plaza Dr. (across from the DTD Marketplace, right behind Once Upon a Toy, the road veers off either to the left or to the right -- Take the right, that's Hotel Plaza Dr.) to 535-Apopka Vineland Rd. (The intersection with a stoplight at the very edge of property.
At that stoplight, you can either go straight (cross 535) into the crossroads shopping center, or you can turn left (onto 535) and go a ways down the road. Past Palm Parkway, there'll be a small strip mall with an Eckerd's, which I believe has an attached store where they sell some wines.
If you continue on 535, past the Eckerd's, you'll find a small plaza with a Winn Dixie and an ABC Liquors. The liquor store has a great selection and pretty good prices, too.
