This can refer to any item or object which is the most commonly used or which you use without having to think about it, such as a food, bag, facial expression, etc. Your 'go-to x' is the 'x' that you will resort to most commonly when you don't have the inclination/time to come up with something more original, or else that you will just go to automatically.

A go-to bag, for example, would be one that went with any day-to-day outfit and is suitable in pretty much any situation. If you're in a rush, you grab your go-to bag.

If you're feeling unimaginative, you eat your go-to food - something quick that requires little effort but tastes good.

The same principle can be applied to pretty much anything.
A: You look grumpy, what's up?
B: Nothing, this is just my go-to face.

A: Dude, all you have in your cupboard is pasta and tinned tomatoes.
B: Yeh I know, I haven't had chance to go shopping - pasta is just my go-to meal.

A: Do you know what kind of glue I should use to stick 2 pieces of wood together?
B: I dunno, I'd just use PVA, it's my go-to glue.

A Japanese assassian from Kill Bill. She protects O-Ren Ishi, one of the 5 responsible for The Bride's tragedy.

She's only 17 but kills without question or reason. She's sexy but her violent nature makes you shiver and creep out.

Even though the character is chilling and psychotic, the actor that plays her is hot! :)
