Time Out says
Located in the heart of Soho, Soupday swears by their double-boiled soups recipes that are full of care, comfort, love, patience, and the wisdom of Chinese herbal culture. For those of you who are unfamiliar, double-boiling is an ancient Chinese cooking technique that is a much slower and more gentle process to ensure that the nutrients and tastes from the ingredients are retained. But if you’re not in the mood for that (how?), they also serve a variety of dim sum and rice congee that are definitely going to remind you of a nice home-cooked meal.
