I've been wanting to make some burgers recently, but the sad state of frozen minced beef at supermarkets makes me sad. As such, I'm now looking to find a place around Ampang where I can get fresh meat from. Any ideas?

usually pasar tani got

village grocer, cold storage & Isetan supermarket usually they sell fresh beef

just to drop a tip, make sure you get some fat. Most prepacked minced beef are pretty lean, mix in approx 15% ratio, you'll not regret it, that's where the juices are from.
