Great food but even better experience!
There is no menu but as long as you're adventurous eaters there should be no problem. If you're not I'd suggest telling them in advance when you make the reservations what foods you have issues with.
We had a spicy soup with rose oil and peppers, a salad with indian spices and a popadom, fish cooked sous vide and an apple tart- the apples were cooked in a tempura batter.
The meal took almost 3 hours but if you're with a group that shouldnt be an issue! The wine is cheap! $6/7 a glass and he'll just leave the bottle on the table- honour system!
The chef is an interesting guy, I'd suggest chatting with him!
Come with a group and consider it your whole evening booked.
