Inexpensive place to eat with hot or cold food and great place to go if you can't afford champagne and oyster at Harrod's across the road.
Try sweet chilli chicken (on the chilli side) with rice or noddles. Very generous portions
Lots of option for vegetarians and vegan.
Small sitting area.
A shame they use an awful lot of plastic and there is no recycling option.
