Need a spot for festive, amazing food, 10 adults (30 to 65 years) from NYC/CT to celebrate the holidays in London. First weekend in December is the timing. We can be a bit loud and don't want to feel out of place but its an annual celebratory dinner and the eldest in our group will want to dress up a bit. We don't want to be put in a private room. Help! Suggestions so far have been River Cafe and Wolseley?? Not french bistro (doing that the night before).
