I went there expecting to be able to order the vege ramen and say "no fish broth". When I did so, they kind of looked at me strangely and one of the kitchen staff came out to talk to me. He said that the fish stock came in the broth, and it couldn't be made without it and offered to give me my money back. When I pointed out that the menu said "vegetable only" (I was hungry at this stage), he disappeared for a minute and when he returned he said it was okay and directed me to sit down.
The food itself was okay, but not fantastic, and while not expensive, it was not especially cheap either. Would not recommend unless something changes.
