Hiya jb, i went to the one in Londons Kensington Olympia a couple of years back and it was great, good food and good drinks from all over the world kitchen gadgets etc... if you're a foodie like me then prepare to spend a pretty bit but in the run up just don't spend a lot in other areas of your life so you won't feel as guilty! lol, They have cash machines there but like lollyone said sometimes the queues can be quite long so like she said maybe take an iced bottle of water with you and what cash you think you'll need and don't eat for a couple of days prior as you will get filled up there, the portion sizes are pretty small but very tasty and the point of is is so you can taste everything otherwise if the portions were massive you'd only be able to sample one stalls dishes and then you'd want a nap! let us know how it went!
