I'm going on an amazing trip in September to London and Switzerland. I've been scouring the web trying to find some great places to eat, drink and be merry. Also, I'd like to find spots that do the local dishes well, i.e. toasties (I think that's what they're called) fish and chips, raclette, fondue, etc. Any advice would be most welcome. Thanks!
p.s. I love street food.
