We are heading to London next month - making a trip to the US Embassy for the new Chowpup's passport. We have no way of knowing how long we'll be there, so reservations are out. We just need a decent place for lunch, where we'll be welcome, in jeans, with an infant and a 4yo (kid's menu not necessary - Chowpup #1 won't eat from them). Italian, burgers, or good pub food would be great. Thanks for any suggestions.
