The Rolling Stones is the best bar we've seen in Tibás so far. Located about 300m west of the park, open from early enough till midnight. Uncontroversial rock music, playstation, relative tranquility. The bartenders actually know what a gin tonic is, and the gin is actually good (tanqueray, beefeater's, not cacique extra concha).
The owner is from Scotland, suffered from homesickness one day, and bought the toilet from the film Trainstopping.
