Not sure where this coffee shop mug house is but you know this little shop is owned by a Coffee Lover. Coffee Lovers around the world would so buy a cup of coffee from this coffee mug house. LOL How cute!
Writing coffee with the "coffee cup stains" is nice. The original stain that makes the "C" was probably enlarged to create the "f", overlaid to create the "e". The nice brown color that remind us of real coffee stain.
