i like Tian Fu steamboat buffet, fresh and nice. they also have cooked food upon ordering $24 (inclusive GST) at Katong.
cheap and you dont mind the food not of quality go marina bay (only stop on the MRT south line) alot of choices. although all buffet but the soup base differs. some even provide transport to & fro from the eatery to MRT station. $12 pax exclude drinks.
ONLY AVAIL FR EVENING
Halal steamboat + BBQ (no smoke in air-con)
at Simei Eastpoint: Han River, Wide variety + cooked food
okay not bad, dinner time, very packed. $22 (with GST)
Paris - serveral places, Taka, Tampines ..... okay pricey okay if you are big eater. Nice and decent deserts
the long stretch of road behind Parco bugis junction, alot of places offering steamboat buffet.
