Looks like adding toppings and noodles in your choice of soup yourself is a new trend nowadays. Tried it for the first time tonight and I have to say that I quite enjoyed the experience. Toppings were fresh and there's free refill of the noodles. We ordered the original rice noodle, the rice noodle in tomato soup and the cold cut chicken in chili sauce - all were pretty tasty. The soup came out boiling and the toppings were the same for the two different soup bases. Our server recommended putting the raw meat and mushrooms in the soup first, then the remaining toppings, and the noodles last. This is a nice alternative to hot pot.
The only issue I can think of is that if you want to pay by debit or credit card you'd have to go up to the cashier and there is only 1 card machine for it. There was a group of people that paid individually and I had to wait 5-10 minutes till it was my turn.
