Banh Mi - Vietnamese sandwiches in London?

I'll be staying near Hyde Park for a week and was wondering if I could get some bahn mi somewhere. Thanks.

I don't know about Banh Mi but if you can't survive a week in London without eating Vietnamese food you're going to have to trek a ways from Hyde Park to the Southern end of the Kingsland Rd, East of the City, nearest tubes Old St or Shoreditch, where on a short stretch of the road are a clutch of the best Vietnamese restaurants in town-about six of them. Viet Hoa Cafe and Song Que are said to be the best of the bunch

Survive a week without them? Who says I can get them where I live? I was just wondering if you can get them in London because they can be tough to find here in the states.
