If you crave roasted meats when you are in Johor, @kangbeehong_1993 is worth checking out. They have a few branches around so just use google map to find which is the closest to wherever you are.
I am a fan of “siew yoke” (roasted pork belly), so it’s a no-brainer that theirs is what I like the most but their deep red coloured, charcoal-roasted, smoky “char siew” is very popular too. You should definitely ask for the half-fat-half-lean cut for maximum enjoyment.
What I also like about this Malaysian casual restaurant brand is the myriad of ways which you can enjoy their different meats (by the way, they also have chicken and duck). For example, you can choose to have it on your preferred noodles (I had mine on curry “horfun”) or with rice. And for the latter, there is plain or chicken rice-style to select. On top of that, you can also order wanton or “shui gao” soups, stirfried vegetables (the tapioca leaves we had that day was enormously flavourful!) and other items.
