Marine Lines resident Mishael Martina remembers the pani puri gulp-down competition she once had with a friend in college. The 22-year-old assistant director managed to have 49 pani puris in one go and yet, lost the bet. This evening, Martina will be fighting for the top prize in a one-of-its-kind pani puri competition in the city. "I'd like to cross the 50 mark this time," says Martina.
