21st is a coffee snob shop. If you like syrups and such, this isn't the place to go. I prefer the 21st downtown spot. The only thing preventing a 5 star rating for this location is I know the downtown spot has sparkling water on tap and this one doesn't.
The coffees they pick are fantastic. I'm always happy.
If you see the Ruby Creamery Espresso available, get it. It's fantastic.
