We go every couple of months because the roasted bone marrow is my husband's single favorite dish in Boston and we both love the bar and the oysters, which are impeccably chilled, briny, and delicious. This trip we ordered the frisee salad, a long time favorite that we haven't had here in a while. My husband mentioned to the waitress that he isn't a fan of the hazelnuts and prefers his frisee with croutons. This is an opinion and not at all a criticism of the kitchen at ESK. The bill came with the frisee salad removed. We told the waitress that we hadn't voiced a complaint, were more than happy with our meal, and my husband had merely expressed an opinion. She said she understood that but she wouldn't charge us for something that hadn't been thoroughly enjoyed. I love this restaurant! It refuses to get old, stale, and lose its attention to service and quality. So thank you ESK and we will, of course, be back.
