inamo - oriental fusion restaurant on wardour... quite tasty but can be spendy depending on what you order but it's worth going for the experience. it's all interactive and you order the food through a menu which is projected onto your plate (it even calculates the bill per person and per table)
This is a rather splendid veggie mushroom extravaganza from Waterperry - a great place to stop for a cup of tea and a wander around the gardens if you're near the M40.
