We had lunch on a Saturday, we called ahead to reserve for three. The location - garden, furniture and artwork give you a sense of exclusive elegance. Service was cordial without being overwhelming, they where prompt and helpful. We missed having some reference / explanation of the building and art work on the menu, and when asking about it the staff had not enough information. We ordered drinks, a starter, a main dish and dessert. We had no trouble with the menu, it met all our constraints (vegetarian, alcohol free, gluten free, lactose free). The food was very good. The zucchini flowers filled with ricotta where fantastic. We also had an excellent grilled octopus, and two types of tagliatelle. A couple of dishes did not meet the expectation: the ceviche was a very good dish, but the name was deceptive since it lacked any resemblance to the taste of a traditional ceviche (no lemon, no onions, ...) and the apple crumble had no crumble, it was rather a "Clafouti".
As more guests arrived, the noise level went up. Added to the background music, the urge to leave came sooner that we might have otherwise felt.
In summary: the place has all the conditions for an outstanding culinary experience with a few tweaks. Build up the story of the building, enhance the value of the artwork. On the food side, correct the naming of some the dishes. And consider the noise level as part of the experience (for example by eliminating the background music when many guests are present).
We paid 124 Euros, including a 15% tip.
