I like coffee that sell in ordinary kopitiam. But 1 particular shop that sell kopi ais, they blend it after mixing it with coffee and susu pekat. It makes the coffee looks nice as it have extra bubble on top.

On side note, if anyone happen to been to a small place in called Selama, Kedah/Perak. There is a shop call selama cafe that have a good kopi ais. Second generation of kopi bancuh
