I'm going to give Roy's an 'exceptional' for sheer historic value as well as selection. This is the convenience store where you can find almost anything you need short of a full grocery store. We've been amazed to find things there we thought we'd have to go to town for. Roy's is perhaps the oldest convenience store in Rome, and it shows. It is rather run down, and in bad repair. However, customer service is great - you'll always get in and out very fast. They have rows and rows of candy - some rather unique - making it our favorite stop for Easter and Christmas stocking stuffers.
This is a very friendly butcher shop with a lot of different cuts available. They also often have seafood and lamb, but we mainly go there for their beef. The meat is always fresh and they will cut it to your specifications. They sell Boar's Head lunch meats as well. Make sure you sign up for their email that lets you know what the daily specials are, otherwise they are a bit higher than you will pay in the grocery stores, but if you stick with the specials, you get better meat at a better price. Very clean, friendly and efficient. My only complaint is that they do not take coupons.
I love shopping at Kroger. The employees are great and check out is always fast. They offer double coupons every day and have other conveniences - like a dvd rental kiosk for 1.00 a day, and change counter. The best thing, perhaps, is that they offer a good assortment of organic and health conscious foods. Great sales, and great selection.
