When I got off the RER C train at Saint-Gratien station, I noticed this small sandwich restaurant across the street and went in. I ordered a Coke Zero, a double cheese burger and fries and was amazed at how very good the food was! There is a small seating area inside and outside, the friendly chef behind the counter smiled when I ordered in bad French and kindly replied to me in English if I wanted mayonnaise or ketchup with my fries. The food was FANTASTIC, the service was FAST, and the atmosphere was super friendly. I was the only one eating inside, but they were doing a good number of take-out orders for customer while I ate. If you are staying at the Ibis, Le French is maybe 50 feet from the front door. And they accept USA credit cards for payment. This place is a true gem! Please try this great place, you will not regret it!
