Thanks a bunch for the last minute recs. That is a nice place. I had the endive and eel salad (suggested by Robert) to start and it was fantastic! I would go back just for that. Lovely fatty eel with a sweet sauce and crunchy bitter endive as a perfect counterpoint. For my main, I went with the udon and roasted oysters. It was good, the oysters were fantastic (sweet and succulent) but the broth and noodles were a little bland. My companion had the grilled salmon, which was much better, perfectly cooked.
Anyway, thanks again.
