My boyfriend and I would always go for Ajisen ramen, it's the most flavorful and all other options in the city serve creamy broth but not tasty!
We tried the ramen here once (I got a plain shoyu ramen + plum wine) and OMG it was divine! The broth was very creamy AND very flavorful! The noodles were just perfectly cooked, meat was soft and chewy and altogether was very filling. the plum wine paired so well with the ramen too.
Despite all that goodness, I'd say it would be nice if there's more vegetables on the basic ramens. I frowned looking at the boiled vegetables side-dish being 4$ as a small addition. Like c'mon vegetables should be cheap! The expensive price is what the lack of one star is for.
