Damn, that's good coffee!.
Whenever I'm in Denver for business I make it a habit to stop by Deidrich Coffee at 12 & Clayton for a Mayan Mocha or a Madagascar Latte. All the drinks are terrific and the food is great as well. I'm a fan of the jerk chicken soup and all of the sandwiches are awesome and made to order.
The thing I like best is the service though. It feels and is a wonderful neighborhood coffeeshop with a great atomsphere. The employees always remember me when I come in and usually remember my drink order as well. I recommend getting there in the morning so you get a chance to meet the manager Maria, she's a knockout.
I'm looking forward to my next trip to Denver already!
