Offering a chance to locals to explore their city, a travel boutique called No Footprints is set to introduce free guided tours. This will be done on the lines of free tours that are popular across Europe, which function on a tip-only basis. Esha Singh, head, consumer operations said, "We have been budget travellers all our lives and have greatly benefitted from the free guided tours around the world. There is no better way to learn about the history of a place. And, we thought it’s about time Mumbai had its own."
