Eeyore goes well between the bread

An apple, a yogurt, a chocolate bar and a sandwich- that has been my lunch every day since I switched from mother's milk to solid food.

Ten months ago, I moved to Beijing. It took me just a day or two to recover from the jetlag - in all but one sense. Every lunchtime left me feeling thoroughly scrambled.

It wasn't that I didn't love the mountains of sticky gongbao jiding, the silky tofu in its clear broth or the fish heads gazing balefully up at me from their bed of chilies. But, somehow, the midday noodles and rice were throwing my body clock off kilter. I couldn't shake off that central part of my daily routine. Where was I to get a sandwich in Beijing?
