On that theme, I ate an Alpaca burger the other day - seriously......not bad, tasted like "Agneau de Sel" (lamb that has come off the mountain and been fed on salty estuary grass - in the UK, you can get it in the Solway Firth area...)
DT - Always fancied having a go at an ostrich burger and the like but never plucked up the courage to actually go and buy one - fear of the unknown, possibly.
