'Shark Tank' judge Radhika Gupta, who lives in Mumbai, visited Delhi recently. Tweeting a picture of her on metro, the Edelweiss CEO tweeted, "What do you [do] when Delhi is flooded on the day you're supposed to have a roadshow?" "Ditch the car for the fabulous metro, enjoy chole-bhatura and rajma-chawal like a Delhi kid, and keep working," she added.
