There is no atmosphere here. It’s located opposite the Food Opera food court, so could be quite noisy. The level of customisation is highest among ramen joints in Singapore. In addition to the choosing the broth, you can adjust up to six other factors (eg. richness of taste, thickness of sauce, spiciness, etc). I went for the Black King broth. Not the most refined, but well, so satisfying and unusual. You either love it or hate it. Because of the more plebeian premises, prices are reasonable, although if you load up your ramen with extra noodles, meat, bla bla, you might end up paying $30 for a bowl of noodles. The friendly staff at Nagi are not naggy at all.
