Having visited Asia and Thailand frequently over the years, I am often disappointed with Thai food in UK as all too frequently it is not authentic. Tom Yum Goong is a delightful small restaurant run by the friendliest people and it serves delicious authentic and very fresh Thai Food. They also have a small but good selection of wines plus Singha and Change beer. We have been going there since it first opened (in those early days you had to take your own beer and wine) and I really can't recommend it enough. Sadly it is never that full, perhaps due to the number of Thai restaurants in South West London. However in terms of quality and service, it my view it is very superior to other Thai restaurants in the Richmond, Sheen, St Margarets area.
