US-based celebrity chef Vikas Khanna was shooting for the cover of his new book Khanasutra at a suburban hotel

Amitabh Bachchan was also shooting for the commercial at the same place. When Vikas got to know that Big B was in the vicinity, he caught up with the superstar.

They discussed food and culture. Vikas apparently told him, "Like you portray our culture through your acting on screen, I portray our culture through food." Some thought for food!
