There’s not a lot that’s gluten free at Yoshinoya because of the soy sauce. BUT, eating in Japan can be a bit of a challenge in general if you’re not A. fluent in Japanese, B. a local who’s figured it out, or C. cooking at home. So, what did I eat? The beef and salmon meal. It comes with a bowl of rice and a portion of grilled salmon and miso soup that are all okay. The beef of course isn’t, but it’s segregated and I gave it to others at my table.
