My regular grocer. A well presented store with a sensible layout with wide aisles. Contrast with the aircraft hangar approach that Giant Eagle has the tendency to build. The place is not so giant that you have to decide whether you have enough time to go back to dairy to get the milk you forgot.
All cashiers are friendly and competent. When you see an employee in the store you can feel comfortable asking them a question. Deer in the headlights look will almost always get you a "Can I help you find something?" Nice.
Meats, fish, deli, bakery, and salad bar are all good. They have plenty of beer and wine choices and often that general area has dedicated staff. Craft beer fans will find a great selection.
Pricing is the one issue for many folks. Loss leaders aside, their prices may be higher than a store like Marc's on some items. For my general shopping needs, the prices tend to be on par with competitors.
Get in and get out fast with a nice experience, and they'll load your groceries into your car. Locally owned and well run.
