Grill Istambul sur Aulnay-Sous-Bois

01/08/2026: No matter how much I love the concept of Onyxia, I unfortunately feel it's impossible to place a large order without at least one mistake. I completely understand that managing such a high volume of orders can be complicated, but every time I've tried to eat there with my family, there's been a problem. And this has been going on for years, without any real improvement. Even when ordering directly at the counter, mistakes are still frequent. It's a real shame, because the concept is excellent and deserves to be executed perfectly. The reason I'm writing this review today is mainly because of an incident I find unacceptable. For the first time, I decided to try the ice cream offered by the restaurant... and I found a hair in my ice cream. It obviously wasn't mine, and feeling it on my tongue was a particularly disgusting experience. What makes the situation even more worrying is that I observed several questionable hygiene practices during preparation: the employee simply rinsed their hands instead of washing them, barely rinsed the ice cream scoop, handled my cone with wet fingers, accidentally broke it in front of me without replacing it, and then placed the scoop on a piece of cardboard before asking me to retrieve it myself instead of properly serving the ice cream. In this context, finding a hair in my ice cream was the last straw. I am extremely disappointed with Onyxia. I used to be very fond of this chain, but this incident has made me reconsider. By trying to offer everything, I feel like nothing is truly controlled. The experience ultimately becomes quite ordinary, without any real specialty or consistent quality that would make me want to return. This is all the more regrettable because the potential is clearly there.
