Mouse for desert?!?!

So tonight is our last night in Madrid... and we were desperate for some simple food.  Luckily we found a great Argentinian steakhouse... and the guys looked after us very well.  We were very early for Madrid dinning... it was 9pm... most people dont start going out till that time for dinner!  Anyways we had a great feed, and were treated to a desert.  It was 'Mouse', "oh" said we?  And then the mousse arrived... we had a great night exchanging my bad Spanish and their bad English and a lot of laughs.... tomorrow onto Morocco!
