Monk & Mongoose is a coffee chain only found in Colorado.
We visited the one located in Greenwood Village and you'll be pleased to know that the structure across from the shop features free parking.

The baristas were very friendly and the store was decorated for the holiday season.
Sammy and I dropped in to do some studying and found it to be an enjoyable experience with music playing at a pleasant volume, and seating area not too crowded. The chain has their own in-house syrups and third-party pastries to pair with the standard combination of coffeehouse drinks.
You can check out the menu here. The prices are not listed, but are comparable to Starbucks, we paid about $6 each for flavored lattes.
