Just take this fucker's opinion with plenty of salt lah. When he has to go to such an extent to fight for his country's dishes, you'll know that this is a loser with no confidence in himself nor in his country.
True connoisseurs who have tried the dishes from both countries will definitely agree that Singaporean dishes (of the same kind available in both countries) have more varieties, ingredients and are also of more healthier choices than their Malaysian counterparts. Malaysia's hawker food are plain Jane with not much ingredients and uses lots of MSG and pork lard, the latter of which is very unhealthy for the heart.
Furthermore, only a few of their restaurants can really make it. For example, in JB, even though under the same Peking Restaurant group, only the one located in Sutera Mall is acceptable for us, whilst their other outlets at Taman Sentosa and Taman Molek, etc, all cannot make it one. I also have yet to come across a truly good, delicious and healthy food restaurant in KL and Penang.
Pre-covid, we went to Malacca for Nyonya food at a supposedly famous Nyonya restaurant. It turned out to be a disappointment because the fish maw they used in their fish maw soup, must have been expired as they tasted and smelled awful when consumed.
