Sorry, TP = Toa Payoh 
Sakura
is also at Tampines (I think) and elsewhere, but I suggested TP bec
it's more central.
Soul Garden will cost about $25 or slightly more including the
++.
If don't mind paying more, eh...Merchant Court has a nice buffet
($25-$30) with its very popular durian mousse. Bookings are a must
though as it's very popular.
These are a couple of suggestions which I had tried before.
