Saw a store located at Blk 269B coffeeshop (near the Kwan Im temple on Waterloo Street). Opp Bugis+ mall.
Not sure whether this is the stall mentioned by bros here. Have not try this stall.
Always eat the curry rice at junction of Kitchener Road/Jalan Besar. Have try others @near the Great World, @TiongBahru @Lor8 Toa Payoh. Still prefer the one at Kitchener Road. Also got ample seating area with good ventilation. After that, can go Mustafa jalan jalan.
