Finally, I'm almost well now. I'm now able to eat steamboat without the rice portion. :D Went to Shi Wei Tian with my colleagues for dinner few days ago and enjoyed myself there. That's the Tom Yum vs Herbal Chicken soup base. They say that Tom Yum is nicer but I didn't take spicy food so, I've only tried the Herbal Chicken soup (+$10 for that soup base) . It's very thick and probably too much herbal ingredients so a bit bitter I felt. Overall the food is nice but portion per bowl is quite small and price on the high side, as it's not buffet. The service is pretty slow as well.
