Greasy spoon by day, authentic Thai restaurant by night. This is an excellent restaurant on the cut and in my opinion 100% the best place to eat around Waterloo station. The food isn't expensive and is very high quality, have only had better Thai in Thailand. It's BYOB too so bring you own beer and wine, with I think a £1 corkage charge. Can get busy and can't book so be aware. Cash only.
