The best walking tours

Puru Das, 49, owns and runs the New Delhi-based architecture and design firm DeMuro Das with his life and business partner Brian DeMuro. The pair’s latest project culminates two years of product development. They worked with India’s gem-crafting experts to develop a furniture collection wreathed in semi-precious stones, large-scale pieces that deploy intense craft.

Das flies around 50,000 miles each year, mostly shuttling among India, Europe and the US. He’s fond of Virgin Atlantic, which operates a regular service between New Delhi and London. Das cites its stellar service as “efficient and yet casual,” but would like to weigh in when the airline next overhauls its cabins. “The upper-class seat design could use a serious rework as it’s kind of baffling, compared to other business-class options.”
