Dating back to 1927, Flury's is an enticing art deco palace that's a real Kolkata institution. The best time to drop by is during breakfast (English breakfast platter ₹670), or in the evenings when you can just drink coffee and eat slices of gooey Sacher-Torte (cake from ₹80). It's surely the only major iconic world cafe to cite beans on toast as a heritage speciality.
