I bought 2lbs of coffee from them every month for almost two years. Now that I moved away I miss their beans! Staff is professional, make great coffees! Not a great hangout spot, but I don't go their to hangout; isn't their fault, it's because of the location in The Source and limited seating, and perhaps parking. At least parking isn't time limited and is free, unlike other areas in Denver.
TLDR: Love Boxcar Coffee! Not best location, limited hanging out.
