Dating back to the 1950s, Haji Kadir Food Chains is known for its sup tulang. Besides the fiery red dish though, Haji Kadir Food Chains offers a wide variety of Malay and Indian Muslim dishes, one of them being the roti john (from $6.50). Here, you get to pick what kind of protein you want stuffed into the fried baguette, ranging from mutton and chicken to tuna and steak. The Roti John Combo ($12) comes with a fried egg and fries, and steak is an option for those especially famished.
Haji Kadir Food Chains has multiple locations in Singapore. Visit its Instagram for more information.
