I'll keep this short because I went last November (2012) and there is one choice I ate there that stands out from anything I've ever eaten.
The Pear Bruschetta. I never thought my favourite food would ever be a starter but the Pear Bruschetta is the tastiest food I've ever eaten in my life and I could just eat it all day long.
Apart from that, everything else was excellent from the staff serving us to the other courses.
