I love char siew too. Haven't try the one at Restaurant Overseas Imbi, coz dunno 1 plate will cost how much. There's a stall at Jalan Peel, which serve delicious char siew and Braised Pork Knuckle. It's located along the Shell Petrol Station at Jln Peel. The stall name is Jia Jia Lai. I've attached a link for easy reference: http://klchin.blogspot.com/2011/02/jalan-p...raise-pork.html
Open on weekends.

Another stall selling good char siew will be at a chinese coffee shop name Uncle Meng. At this shop, got many other stalls and one of it is selling chicken rice/char siew rice. It is located at Taman Shamelin Perkasa. If u know the cafe Pat Kin Pat San which is at the front row, then this chinese shop is located at the end of the row. U'll see this Uncle Meng shop, and the char siew only available around 11.30am onwards till sold out. Not open on Sunday.

U meant Jln Peel stall or Uncle Meng stall? I didn't eat the char siew at Jln Peel for quite some time d (more than a year ago), but the last time i eat, the char siew is tasty and especially the braised pork is delicious. As for Uncle Meng's stall, my parents tar pau almost once a week, i eat a bit of the char siew, and taste just nice. I like roasted meat (siew yoke, roasted duck, char siew), just wondering where got stalls/shop which sells good roasted meat at night (still available after 8 or 9pm) around KL/Cheras area, anyone knows? Coz most stalls will close after lunch time or some shops also close by 7, 8pm.
