Not just uniform. They have their own Chilli Sauce / Ketchup buns etc. Either repacked / relabelled or made themselves i got no idea. And its everywhere around Gombak!

No idea about Puchong but at my place, there are like about 3 - 4 Otai stalls in just a small radius. Tried a couple of them and not by any chance near those great ones i tasted back in those days when i am staying at SS2. The one opposite of the SS2 Police Station still have the best burger i have ever tried, followed by the one at the Fire Station.

Personal preference The stall is at the Indomee roadside stall. I love getting their "Full House" burger (thats the name the owner told me) which consist of 2 patties, 2 eggs and cheese. Used to cost about RM5+ and absolutely heaven especially during midnight study revision times . Not sure about the price nowadays though.
