Not much problem with that. Soho Chinatown is an excellent centre for Asian groceries and ingredients. I go quite often to restock on ramen and stuff. 5-10 minutes in either direction to Trafalgar Square and Oxford Street, with Leicester Square next door, so it's a convenient meeting place too, grabbing a bite from one of the nearby food shops while I wait. And if you're of that bent, Shaftesbury Avenue aka the West End is on the other side of Chinatown, so you can literally cross the road and have your pick of the big theatres. I've heard that 30 years ago Chinatown was even more of a centre for Asian culture, but most of that seems to have been assimilated into the semi-mainstream, with Chinatown itself mainly a centre for food. Good food though.
