This restaurant is definitely NOT all vegetarian. For someone not confident with Japanese kanji, you will have the choice of ordering the "lunch set" or "lunch deli". As far as I could tell, the set is the same but includes a drink and a dessert. The menu is incredibly hard to make out, and limited. The veggie deli options change regularly, but you don't get to choose what items come on your plate.
When I ordered the "lunch deli" I had a well presented and delicious plate of mystery salad (which I think is fun!) including stewed ginger and mushroom potato salad. The main was disappointing - just some brown rice in a plain tomato curry sauce. Something not very unique or special.
The staff were not welcoming, the largely ignored myself and my partner, despite us smiling and making our best efforts. I really wanted to like this place, but I won't be returning again.
Cons: Very limited menu, No English, Rude and dismissive staff
