Call me a grumpy old cynic by all means: I just read this article about a new "concept" restaurant in Brighton, Street Thai.
Big Hospitality, 29th November 2010
It promises "authentic" Thai street food which the manager/executive chef describes as "affordable, simple and super tasty”. I've googled to try and get an idea of prices but there's absolutely zilch on the net. You can bet a penny to a pound though, I'm sure, that it won't work out much cheaper than flying to Bangkok for the real thing!
