This I am not sure bro.

no pork whatsoever, but no halal cert.

u know la, a lot non bumi business also hard to get halal cert.
coz need to change all equipment & hired % of bumi staff.

PH pastry house at sg. besi also worth checking out.
also non halal, coz got surve alcohol on menu.
but no pork, also got malay staff, chef is malay, & a lot meleis also eat/buy food there.

speaking of sungai besi, bites is another great breakfast/brunch place. just opposite of ph pastry house.
but non halal & got bacon la.
though i'm not sure chicken bacon or pork.
