As noted, the restaurant is accessible through the Fancl International shop. I hadn't realised that there were 2 options, we went up to the 'posh' restaurant on the 9th floor. I was very unsure about the portion sizes but our waitress was quite helpful in reasonable English. We settled on the cold tofu with Udo oil to share between the 3 of us, and the soup of the day each (gazpacho) my non-veg*n dining companions enjoyed the tofu but thought the gazpacho could have been more seasoned. I liked both, the soup was perfect for the hot humid day we had endured.
I then had the Gluten pieces with vegetables which were tasty but we failed to realise that we should have ordered rice on the side so consequently our main courses were quite small, we made up for this with a dessert, again quite a small portion compared with back home but the avocado pudding was delicious.
On the whole very nice. Costing ¥6200 for me with 2 beers
Cons: Reservations probably needed, we got lucky
