And this time I also tried the Bistro Mazarine.
I went there for coffee twice and for one meal.
I only had one course - Steak Tartare which was fine.
I found it to be a very pleasant bistro - not very busy, pleasant outdoor seating and by far the friendliest staff I encountered.
I will certainly come back.

A restaurant in Versailles that I won't recommend : Chez Lazare.
