This place blow Starbucks and other chain coffee shops out of the water.
First it's the staff. It's a small group of baristas that are amongst the friendliest and nicest you will encounter in any type of customer service role. They remember their regulars and always have a happy demeanor, even if the shop is insanely busy. Oh! They make great coffee too.
The menu has all the typical coffee shop norms. I especially like some of their more creative flavor combinations like "The Sith" which is mocha and peppermint, or the "PBJ" which includes REAL peanut butter along with banana flavorings. They also have some food options including healthy wraps, and the normal pastry selection that is to be expected.
Decor is nice and inviting. This place is huge in the Vegas tech scene. You'll often find developers working hard on their Mac's, while some film guys discuss their latest project they're working on. They have a ton of books and games that you can grab up and enjoy, as well as a tv playing something geeky on the AppleTV. Plenty of comfy seating.
If you're looking for good coffee, great service, and a cool place to hang out that ISN'T regurgitated Starbucks, this is your place.
P.S. I've met the Grouchy John, and he's FAR from grouchy!
