that is particularly true of something like ramen which has a lot of regional variants.
i personally would prefer to eat in osaka with their ‘eat until you drop’ (kuidaore) philosophy. you won’t necessarily go there for a lot of fine dining vis a vis michelin rated places, or for say, sushi, soba, tempura etc. which are edo period categories, but the diversity & quality of the every day snack/street food puts tokyo to shame. and it’s all affordable.
