Around 15/16 € for ramen excluding supplements. Add the drinks. Two people usually go out for just under € 40 for the meal.

No, it is not possible to come with animals.

I have already seen vegetarian ramens on the menu but they are limited editions. However in each ramen available there is meat but it is quite possible to ask not to put in (or to replace it with a normally paying supplement). I think, however, that there is a ramen with pork broth I can not remember which, in doubt it will be enough to ask the chief.
