I know that Ramen Jinya makes a veggie (including no fish/bonito) based ramen. But is there anywhere else noteworthy that makes a purely vegetarian soup (that is worth eating)?
I had high hopes for the spectacular roasted miso ramen at Mottainai in Gardena, but when I called them my conversation went something like this:
"Hello, is this Mottainai Ramen?"
"Yes, yes. Mottainai."
"My friend is vegetarian. Do you make your miso ramen without meat or fish?"
"If you want vegetarian, please order with no chashu pork."
"But does the soup contain fish or pork bone?"
"Only order without chashu, vegetarian."
"But is the soup made with any fish or pork?"
"Ah. Hm, if you want to order this, then please try go somewhere else."
