Wikipedia[1] gives the year only - "The Leopold Cafe was founded in 1871 by Iranis" - and its infobox agrees, with no month or day, so the pin sits on that year's last day.Leopold Cafe was founded in Colaba in 1871 by Irani immigrants, part of the wave of Zoroastrian cafes that shaped how Bombay eats out, and has outlasted almost all of them. It became a fixture for travellers along the Causeway, and was one of the sites attacked in November 2008 - it reopened days afterwards and kept the bullet marks in its walls.
