Chedraui
Open daily from 7 am to 11 pm, this big, full-service grocery store also carries clothing, kitchenware, appliances, furniture, and a terrific selection of wine. For those renting a nearby condo, this is a place to stock up on food and beverages. Brand-name sunscreens, while expensive, are available. The deli and bakery are excellent places to pick up picnic provisions; coolers and ice are sold here, too.
