For cocktails How to Drink is really fun - totally unconventional and he gets hilariously tipsy. The dude also seems like a sweetie! But when you said experimenting he was my first immediate thought.
The ANTI-CHEF also deserves a shoutout, if only for daring to try to finish a Julia Child's cookbook. Again, not a very conventional chef... if I recall correctly in fact this YouTube channel may be how he is learning to cook... :D
