Not sure if this is still under same operator but I see all the bad reviews and thought I'd chime in since I visited for a snack a coupe of times in 2014. I asked for Murtabak and while I got something that looked like Murtabak the filling was really more like that of Chinese Pancake in a Roti shell.
Now I must say they did make it fresh, which is why it took a while, I could see them roll & shape the dough in the mostly open kitchen behind the counter. I half expected to get something prefab and warmed up but that was not the case, It wasn't bad, it just wasn't Murtabak.
I don't think these are bad or incompetent people, they're just over-reaching in trying to offer the Malaysian items (and probably the Thai ones as well) with only a vague, beginner's knowledge of the spicing, ingredient ratios and prep nuances of these dishes.
I understand they're in a food court surrounded by other Chinese options and a dozen more across the parking lot so there is the temptation to differentiate themselves somehow, But it's fair to criticize them for not having the motivation to learn & improve a little over the years.
Bottom line is only go there if you're super hungry, in a rush and the line ups are long at every other counter and don;t order anything exotic or ambitious.
