We went to this place because our friends' daughter has celiac disease. Well organized place, the waiters are young but trained and helpful. They let us sit outside, a perfect place for the children so as not to disturb the other patrons of the place. Good food (burgers) and at the right price. I got the black burger and honestly it's a man vs food thing... so my advice is to stick with something smaller like the red burger.
Finally, to my wife's satisfaction, they also accept payment with satispay, so the evening was pleasantly spent.
If we can give some advice to the waiters/owner, pass between the tables no more than once every 2/3 minutes, it makes you anxious to pass one after the other every minute. Then you understand that they are young guys (and super polite/prepared) but the customers feel the owl on their shoulder...
