Love Spanish food, but often it’s really nice to branch out a little.  French food is always a good option, but it’s hard in Madrid to find authentic bistrot food…and impossible at a good price. 

A great French bistrot experience can be found at Le Petit Bistrot. 
Two locations: 
Calle Ponzano, 60
Plaza Matute, 5
