Pho Dien appeared on our list of the ten best bowls of pho in Houston back in September of last year, and it also won the Best of Houston honors for having the city's best pho in 2013 and 2016. So what makes this noodle soup reign supreme again and again? A consistent combination of fragrant, clear broth, high-quality proteins and other ingredients, and a restaurant with a mom-and-pop look and feel that continue to attract a line of diners stretching out the door every day. Bowls are big, at $7.75, and a serious bargain.
