The OP Market is located in a residential neighborhood that does not have a large grocery store. It stocks the staples such as bread, milk and baby diapers as well as a selection of packaged foods and snacks. It brews fresh coffee and makes European style espresso and cappuccinos. It offers a variety of fresh-baked pastries as well as a small selection of deli sandwiches. It also sells beer and wine, soft drinks and party supplies such as chips and snack food. Its central location and hours of operation make it a popular stop for basic items before returning home. There’s an ATM and it’s an official dealer for CA Lottery sales. It also is a member of the Money Gram, a money wiring service.
