I went, and it is everything that they say it is. The flammekueche is out of this world. I had never had one before, so the only thing I can compare it to is pizza. If it had tomato sauce it would be the best pizza in town. as it doesn't have tomato sauce, it is just something really delicious, a combination of savory flavors on an exquisite thin crust. While the Mirror thinks it should be slightly more blistered, the one I ordered (forrestière, with mushrooms) was structurally and texturally perfect for me.
Then I ordered a burger, and sure enough it was ground to order. Does anyone know if there are any other restaurants in town that grind to order? At any price point? It was about the juiciest burger I have ever had in my life. I can only attribute that to when it was ground, because from what I can find, the haut de surlonge is not particularly fatty. The bun is baked in house as well and the idea that it is under $10 is just amazing.
The fries are nothing to sneeze at either - while I'm not a great fan of fries, they certainly were crisp, golden and tasty. They get served with some mayonnaise (although not quite enough in my estimation) but if my only complaint is that there isn't enough mayonnaise served with the fries, then it truly is a really good place (I did ask for a second paper ramekin, which was brought promptly). Then once I factor in price, I get pissed off at myself that I don't live closer, because it might just be the best bargain in the city.
Apparently they have a table de hote which changes weekly, I'm looking forward to trying some of the offerings on it, but given how good the flammekueche and burgers are, it's not going to be an easy choice.
