Lviv is Ukraine's undisputed coffee capital, and the 'Lviv Coffee Mine' is where the stratum of arabica is excavated by local colliers from deep beneath pl Rynok. You can tour the mine or just sample the heart-pumping end product inside at tables as dark as the brews, or out on the covered courtyard.
The complex also has a coffee-themed shop and a section where you can purchase recently mined and milled beans.
