After an absence of a couple of years, I will be visiting London with friends in late April and we want to try the best Indian restaurants in London. Price is no object. In past trips to London I have enjoyed Zaika, Tamarind, and Benares, and been unimpressed with Cinnamon Club and Khans. I am happy to enjoy "tradtional" Indian food as well as the more stylist food served in some places. My group includes both vegetarians and meat eaters. Any thoughts?
