I know places

The best song off 1989, it is so underrated and Taylor’s performance in the tour is absolutely incredible

Person 1: ‘I know places is such an amazing song!’
Person 2: ‘yes!’

I know this place like I know my baguette

This expression is a derivation of the french expression "I know this place like my pocket" which is an equivalent of " I know this place like the back of my hand" meaning that a person knows really well a place.
Works better if you are french or a baker.

-Do you know where we are?
-Yeah of course. I know this place like I know my baguette.
