Gilgamesh learned a lot on his travels through the Interdimensional Rift, including culinary expertise! As for Golby, well, someone has to look after Cecil so in his time he's learnt how to be a decent chef in order to make sure his baby brother stays well fed. Also his Japanese VA hosts Iron Chef... Gabby, well...I guess he needs a hobby since he hardly works for Chaos these days. And the kitchen is a place for REAL MEN! MENLY MASCULINE MEN WITH TESTOSTERONE WHO PRODUCE THE MOST SUBLIME, PUFFY, GOLDEN PROFITEROLES YOU EVER DID TASTE!
