My wife and I are looking to improve our skills in the kitchen. Are their any recommended cooking classes in Manila?

Sounds like a fun idea! Try The Cookery Place in the Fort. Here's their site: http://www.thecookeryplace.com/ They offer couples cooking classes (http://www.thecookeryplace.com/#!about/cjn9)! They've received a lot of great reviews, too. Have fun!
