If you’re a fan of Sichuan’s “ma la” flavor—the spicy cuisine that numbs your mouth, paired with lots and lots of garlic—this is a restaurant you can’t miss. The original is a tiny shop in Sham Shui Po, but we simply had to go see whether this newly opened branch in Mong Kok could maintain the same standards. We went straight for their titular dish, the “heart-breaking sour and spicy noodle.” Yeah, heart-breaking because it’s so sour and hot they reckon you’ll start sobbing out of reflex. There are four degrees of piquancy to go for and we decided to keep it mild—still hot, though. The generous portion of minced pork and peanuts in the broth kept us going, despite the heat. Our favorite side dish was the “mouth-watering chicken,” served with a house-made hot sauce with special spices to bring the plain steamed chicken to life. We also made a bold move and tried something a little different—the 1,000-year-old egg served with pickled chili. Unlike the usual stinky old eggs, Heart-Breaking’s is more like a smoked egg with a runny orange yolk and a translucent white. The smoky flavor blends well with the green chili, and lots of garlic. The only drawback here is that the tables and chairs are too small, making it extremely crowed during peak hours.
