When two pho restaurants sit in the same city, there is bound to be competition. The splash of soups. The abomination of spices. The tanginess of the sauce. The Nguyen and Mai family have been at each other’s throats for so many years, yet a love story blossoms between their young children. Written by Loan Le, “A Pho Love Story” projects a Romeo-and-Juliet story where an unlikely romance is forged from rivaling pho restaurants.
