Thai food is truly one of the world's 'great' cuisines. There are a vast number of traditional Thai dishes - far too many to mention here - however it might be safe to say that typical thai ingredients that impart the usual flavours people associate with thai food would include things like fish sauce, chilli, lemongrass, shrimp paste, lime, coconut milk, peanuts. Probably the best known thai dish (at least to westerners) would be Pad Thai - which means 'Thai style noodles' - this might be a good dish to start with to introduce yourself to Thai food - it has a good combination of classic flavours and is not really spicy.
