The march of the burrito chain continues apace. Burrito Café starts with freshly made salsas and guacamole, adds moist pulled pork, grilled chicken with a hint of lime, or barbecued beef (sautéed peppers and onion for vegetarians) and wraps it all in a floury tortilla. Handy for the Strand's many theatres and for those famished workers dashing to catch their commuter trains from Charing Cross.
