The first place that I wanted to go back to is King Laksa steamboat near Upper Serangoon Road. The actual address is 17 Teck Chye Terrace, Singapore 545724. It's a buffet all you can eat concept, and if you're a big eater you can keep ordering and ordering. In any case if you're sick of the Laksa, you can try their other soup as well since it's a Ying Yang concept whereby you can order 2 soup base.
The other one is 山Laksa steamboat seafood restaurant which is near Telok Blangah. It has a 海底捞concept whereby they'll charge you for everything you order. If you're going for quality and not quantity then you should give this place a visit. The isn't frozen, and the slices are of a more premium cut (what do you think for the price you're paying for)
Hopefully within this few days I can satisfy my cravings at either of it. Or maybe I can go Shanghai tomorrow to satisfy my steamboat carvings at 海底捞 :)
