No, unlike Harvey Nicks with its fab luxury food & grocery section, Tangs doesn’t have one. Instead, its basement level with its household/kitchenware department also has a good, smallish food hall with some very popular food kiosks: a Nyonya one (my favourite spot) by PeraMakan restaurant group, one offering Singapore-style Hokkien noodles, one which does a Singaporean (i.e. heavier, gluggier) rendition of Penang fried kway teow noodles, a “Penang” cendol and rojak kiosk (somehow, they can’t replicate the cleaner, keener flavours one finds in Penang), a steamed bao & dimsum kiosk, a Hainanese chicken rice one, etc.
I guess the food hall reflects Singaporeans’ lifestyle - who are more likely to eat out than cook at home. So, food kiosks with hot, ready-to-eat meals are more relevant than a supermarket. 90% of Singaporean women can’t cook anyway, or don’t want to, so grocery shopping is not really as important.
