The Coughlin Ranch Scolari's might be the best all around local groc store in South Reno. Friendly, helpful staff, store is always kept clean. The food prices are of course higher than a WalMart, WinCo, or Costco, but for that you get better produce quality, wider variety with specialty items and the like, a cleaner shopping envirnoment, and they have a decent deli section/bakery to boot.
Pros: Great all around
Cons: Prices are higher than big-box stores like WalMart or WinCo
