I've eaten here three times. The first two times were outstanding. The third time was not a charm. The food was almost inedible. Our first course was a dumpling dish that had so much wasabi in it that I was in physical pain trying to eat the dish. The second course was an inedible fish dish. I don't think the fish was fresh. The waitress, to her credit, saw that we were not enjoying the food and took it away. We asked for the check and finished our drinks...we didn't complain and were not going to make a scene.
This is when things got weird. The chef (owner??) came out and insisted that his food was good. To prove it he insisted that we sample some other dishes. He brought some sort of fish stew that was inedible (again the fish wasn't fresh)...At that point we paid the check and snuck out of the restaurant before he could serve us any additional food.
I won't be back. It is a shame because the first two times I ate at Sens the food was delicious. However, the hallmark of a good restaurant is that the food is good every time.
