I don't mind the Ramen at Wagamama's. The best dish they have to offer imo is most definitely the Seafood mix ramen! Crab, mussels, prawns, mmmmm etc etc. So many more yummy ingredients. I would recommend going there for dinner over lunch tbh. Why? The bowl's are fricking huge! If you go for lunch, you're definitely going to bed without the need for dinner. xD
I haven't been to Wagamama's for a long time. I hope they haven't changed their dishes too much.
I actually buy the Clearspring Instant Ramen, then add new ingredients to it such as wasabi (added to the broth right at the start of cooking), mirin, tamari or shoyu, ume plum seasoning, toasted sesame oil, rice vinegar, and miso (added to the broth right at the end of cooking after I add a little cold water so as not to kill the koji).
