Verdict - Banh Mi 11 are old timers to the relatively young streetfood circuit, having peddled their Vietnamese baguettes in Broadway market for the last few years now. Now with a new home on Berwick street market during the week, you can enjoy their excellent banh mi. Coming in a variety of flavours, I went with the Imperial BBQ which was packed full of herbs, chilli, pickles and meat. Highly recommended
Cost - Between £4.50 and £6
Location - Berwick St Market during the week, and Broadway market on Saturdays I believe. Keep an eye on their website or twitter account for details.
