I'll just chime in that there is no "best cup of coffee." (although I'm always in search of the perfect cup)
Coffee, like food, varies every time you have it. Matthew (DCE) is correct to point out the distinction between espresso and "coffee," which is usually referring to drip coffee.
At Ray's Monkey House Coffeeshop, we carefully cup all of our coffees prior to purchasing the green beans, then buy only the best of the best. THEN, we roast them on premises. So most of our coffees are served in the 4-10 day old range, which I believe is the peak freshness and flavor profile for most coffees. Again, every coffee is different. And coffee doesn't like to sit on a supermarket shelf for months. You can REALLY NOTICE the difference. Some shops in town won't even tell you where they get their coffee. They should be proud of it, not scared to tell! I know Matthew appreciates local fresh coffee, and purchases from local roasters (including me - thanks matt!).
I recommend (I wrote it pretty big on our menu board too!), that people drink french press. We offer it in two sizes, 20 ounce and 32 ounce, reasonably priced. It provides peak freshness, because it is brewed literally moments before hitting your cup. Further, there is no paper filtration (that removes oils from the coffee, affecting flavor and mouthfeel).We bring the french press to your table.
One could go on forever. But a final note might be that espresso is a preparation technique, a method of brewing, and not a different bean. Yes, most of us (myself included) do make special blends for the coffee we use to prepare espresso or espresso-based drinks, but one could also prepare espresso without blending. I currently have some Yemen Mocca Sannani, and Ethiopian Sidamo Korate that both make wonderful Single Origin espresso shots (and drinks).
As for polling, that ends up being a popularity contest. WLKY did a "best of" poll a couple months ago for Louisville. My personal ratings differ substantially from what the people voted for (though I was extremely pleased that Ray's came in third place as a one year old shop - and we almost got second). Popularity contests seldom determine quality, but they are interesting and can be fun. Here is a link to their results....
