I've been getting coffee from Ron Cortez for years. He is very knowledgable and loves teaching people about coffee. The location is kind of hidden in a strip-warehouse, but once you step inside you can tell it's the real deal.
Usually there are a few different single origin and blends available. I prefer African coffees, but he also has a Sumatra that I like. They sell bags of coffee and refrigerated bottles of cold brew. Occasionally you can get a pour-over or an espresso, but most people come here to get coffee to take home.
