After a day out being a tourist you need somewhere to relax and have a beer while decompressing.
Bull’s Brothers Pub in Saint Michel was that place for me.
Bull's Brothers Pub, Saint-Michel, Paris, France
During happy hour (4pm til whenever) you can get pints of Belzebuth Blanche and Königsbacher Pilsener for €5 and €6.
I probably ended up here 4 evenings during my week visit.
Staff are friendly but busy… so it can take a while to get table service but if you are looking for a local during your visit, this is a good place.
