A friend of mine is soon visiting Fukuoka and would like to sample the famous local yatai food stalls:
However, she's vegetarian, while most of Fukuoka's famous dishes (Hakata ramen pork noodles, mentaiko cod roe etc) are not. Browsing the menu of a random stall, they do seem to list a number of vegetarianish items (moyashi itame stirfried bean sprouts, nasumiso eggplant with miso, etc), but knowing Japan, many will actually include bacon and other surprises. To calibrate the difficulty level, she's ok with traces of dashi/stock etc, but not actual chunks of meat or fish.
What vegetarian dishes can you expect to find at Fukuoka's yatais? Recommendations for specific yatai also welcome.
