I got to know about 田楽 from Taiwanese bloggers.
Chenyee aware of their presence too but didn't manage to locate them when she was in Taichung 2 years ago.
Dad had fried shrimps burger.
The rest of us ordered their house special vegetarian burger -tofu burger.
It comes with a whole piece of mushroom too, plus their homemade gravy.
It's very nice, we enjoyed it very much!
