For all the times I've eaten at Uncle Leong (back when it was still at Ang Mo Kio), or Mellben, I never thought to hit up "the other coffeeshop" in the estate, a sad-looking eating house devoid of customers that's on the furthest end of Mellben, and directly opposite where Uncle Leong used to stand.
Apparently, there's a worthwhile kway chap stall in said coffeeshop, one that attracts out-of-towners, and not just the immediate heartland.
For the uninitiated, kway chap is more than braised pig innards, which many are, naturally, averse to. I wouldn't consider myself a fan of innards either, but I love kway chap, because, it is possible to enjoy kway chap even if I balk at the idea of innards. I love the thick flat rice noodles, the delicate braising sauce-based broth, and assortment of braises like beancurd, eggs, and pork belly, all of which are perfectly "normal" and "regular" things to eat. In fact, if you stick to just picking the beancurd and eggs, you could have a vegetarian-friendly meal.
Lao San Kway Chap is one of the better ones I've tried, rustic but balanced, and not too heavy on the herbal elements ($14). We really liked the chilli sauce, the piquancy of which was a wonderful contrast to the dark soy overtones of the dish.
We had the beancurd puff (tau pok), firm beancurd (tau kwa), soy egg, and pork belly, all braised to perfection, and the latter was, in particular, meltingly tender.
The kway teow wasn't the most refined, but it was smooth and slippery, a textural slamdunk.
