La Bicicleteria is a must see spot for people in search of the underground. Anything could happen to you in this tiny illegal bar hidden on the Calle Feria, and it probably will. Find the hidden metal door, ring the buzzer which lights up the door bell light bulb, and hope you get let in. If you do, skin up a joint, and settle in to some good old fashioned, indoors smoking, indoors joking, indoors late night toking. Great music as standard.
