We tried the rich lobster broth which was simmered for hours to obtain the rich orange colour. The full bodied broth have a good taste of lobster and reminds of lobster bisque. Full ingredients option were chosen that came with things like shrimp wanton and chicken chashu not normally found in ramen.
The spicy miso version was tad overpowering with the chilli taste proving too strong for the lobster flavour. Do go for the clear or rich soup to get the best out of this ramen joint which is what the snaking queues of people are here for.
