The allergy of TEMPURA Japanese-style food is taught to you.
I introduce information of food allergy.
This time is tempura.
The nice restaurant I ate gluten-free tempura was "Tofuya Ukai" in Kanagawa.
1-18-4 Saginuma Miyamae-ku Kawasaki Kanagawa
They don't usually serve gluten free tempura but if you ask,
probably they can make it for you.
