The Olive Bar & Kitchen in Mumbai is something of a landmark. A place where the city’s happy people congregate to dine well, to dip into an outstanding cellar, and to linger over laughter and conversation. Just like the city, Mumbai’s Olive is a bit of a chameleon: at Bar Nights on Thursdays, the place explodes with music and high spirits. But visit for Sunday Brunch, and it’s lazy laughter in a sunlit courtyard, where no one will hurry you from your table.
