For me personally:
- it tastes like an authentic bowl of tantan men from restaurant (doesn't feel like it came from an instant pack!)
- very flavourful (sour, salty, sweet, spicy - you name it all)
If you like food with strong taste, this is for you

I thoroughly enjoyed the noodles, but next aiming to try the Tsuta soba cup noodle...!
That's what most of the reviews say - the instant noodle isn't even half as good! Apparently noodle was little as well, pretty plain too. Taste was also pretty off from the real thing.
Oh wow, so lucky that you got to try both Nakiryu and Tsuta. Tempted to try Tsuta in my last trip @ Tokyo but was dreading the queue and we were a big group - thus decided to give up

...was in Singapore for a short work trip before pandemic, and I saw Tsuta there too. But then it was empty and quiet. Friends told me it was just alright, thus didn't go in.
saw some selling for rm30+ in shopee. might give spicy a try 1st
