French Dining, Iidabashi フレンチダイニング 飯田橋
You would think that they could have thought up a more original name for this French restaurant situated not from from Iidabashi. Anyway the staff is mostly French which lends an air of authenticity. I have been for lunch quite a few times and there is always an interesting lunch set on offer with friendly and efficient service. Worth trying out for lunch if you are around Iidabashi.
