My local 7/11 is great. A little pricier then a bodega, but more pleasant in both the workers and the atmosphere. While it's not a supermarket you are likely to find anything you need from a quick bite to eat, to various flavors of coffee, to over the counter medicinal things, a quick fix for your car (oil, power steering fluid, brake fluid, antifreeze etc) being able to purchase gift cards, there is a large variety of necessary things that are usually located close to where you live and open at hours most other stores aren't.
