I always research the latest reviews for places to eat, even when I know several and have options suggested by locals. Even though they have been around since 2010, I would probably not have found L'Aller Retour without some online research because it has a tiny entrance on a small street near the Carreau du Temple. It was definitely worth the search because it was one of my favorite meals during the last trip.
Classic escargots for 6 Euros were perfect in every way, and I even got a friend to try one for the first time because of the buttery garlic aroma that perfumed the table upon their arrival :)
My friend appreciated the quality of the meat in the burger for 14E50 as well as the crisp fries, saying it was very good in spite of it not being well done (for an American-it was well done by French standards, which means it was pink in the middle instead of red).
I had come specifically for the knife cut Charolais steak tartare for 14E that was the best one I ate during this trip. The large salad was very much appreciated to help balance out the meat, with a very nice vinaigrette dressing.
Ending lunch with an espresso was a perfect way to cap off lunch at a newly found favorite.
