There are plenty of reasons to go nuts about this good-for-you fast food concept from the people behind Bunga Bunga and Mr Fogg’s. A healthy eating champion which actually has a sense of fun, Squirrel offers its turmeric latte-sipping customers a tree house to sit in, surrounded by twinkling acorn lights and overlooking the local treetops. The food menu, based on wholesome salads and grain-based bowl food, is supplemented by weekly changing hearty soups and stews. The staff have a basic knowledge of nutrition, so if you want to keep your energy levels up after a workout, for example, you can expect to be pointed in the right direction. Squirrel is open from 7am (to catch the early-bird gym bunnies) to 9pm and also offers a takeaway option, but why would you leave when there’s a tree house?
