Just getting in feels like a triumph! There was a line every time I passed so after reading reviews, I thought I had to try this single-dish restaurant. Ie, steak or steak. (No, you do not get a choice of cut or sauce or anything other than 'cuisson' ie the way you like you steak cooked. I chose 'a point' ie medium rare) . I didn't even know how much I would be paying but there were office workers and students so I figured it wouldn't be crazy expensive, and it wasn't, 22€ for the steak and all you can eat French fries ("frites à volontier'). I rarely eat red meat so although delicious (a very buttery secret sauce) it is super heavy. How people finished it all and asked for more fries, I have no idea.

The experience and expectation makes the food taste better. Standing in line was social and at least 2 sets of tourists asked why the queue and all regulars told them it was well worth the wait, which built up expectations. After about 20 minutes a whole lot of us were allowed in, we were all assigned the top floor.

Despite being so busy, staff were incredibly friendly (I had expected stroppy service). They are happy to explain and seem proud to work there, and they are super efficient.

It's an experience I will repeat next time I'm in France but it is so rich, I think one visit per visit to france is enough for me.
