Ah, I love hole in the wall restaurants. Que Ling is a hidden gem in Riverdale, right by the high school. It's a great place to get authentic and tasty pho on the east side. The broth, noodles & toppings very flavourful and delicious. Don't let the exterior throw you off (it looks like the restaurant is built upon an old backyard shack/hut - it is a cute and cozy family owned restaurant inside. You feel like you're having some home cooking when you're here; which I like. Just as a couple of notes, the Vietnamese coffee is super potent so make sure you can take caffeine well or don't have it after 3pm (or in the evening before you sleep). Also, the place only takes cash so be mindful and bring cash to the restaurant.
