Kacang Pool Haji needs no introduction. I went to the latest outlet at Taman Dato' Onn and tried Kacang Pool Kambing. Yes. Mutton gravy instead of beef. Priced at RM8.00, quite steep for a rather small bowl but it does taste good.
Location: No. 12A, Jalan Sabar, Taman Dato' Onn, Larkin
ps One of the bust curry mutton I've ever had was at Kafe Kejut (a.k.a Fakulti Kejuruteraan & Alam Bina) UKM.
