I picked Chez Marie Louise based on TripAdvisor's reviews. We were on a month long stay in France so we were not in a hurry. We walked most of the way from St. Germain to the 10th Arrondissement. The area where the restaurant is located is not great. Based on that we lowered our expectations for the experience and the food. When we passed the restaurant we were surprised that it looked so "average".
Inside was different in that the welcome was warm and when we were served the food was excellent. But, it still looked like a NYC dive-bar.
The service was a bit amateurish with a young man learning his trade but we were patient with him and it was not a bad experience at all. I did tell the owner that this was among the best food I had in Paris this trip.
There was a woman sitting outside the restaurant dining but also doing what seems like most Parisians do, she was smoking and blowing smoke into the restaurant. That nearly ruined my dining experience. Expect this wherever you have outdoor dining in France.
