Mireille Oasis Sarl sur Olonne-Sur-Mer

I'm going to give you a detailed review because I think it's the first time I've ever been this low, and it deserves to be precise because behind this review are hard-working men and women in the restaurant industry. We had a reservation for 8 people at this casual, open-air restaurant near Les Sables d'Olonne. Upon arrival, there was no welcome; we waited 5 minutes standing in front of a band. No worries, we're patient, it happens. Once seated, we were offered drinks a good 15 minutes after our arrival... never mind. We were served fairly quickly after that. For our order, we had to wait another 15 minutes. Not everything is on the menu, and not everything on the menu is available. Anyway, everyone found something they liked... And then began an interminable wait... at least 45 minutes. We saw two people sharing the tables. There was no sense of energy... no efficiency, but they were smiling. The food finally arrived, and that's when the disappointment set in. The cod was very mediocre, the grilled and flambéed eels were nothing more than something dry accompanied by three steamed potatoes, the frogs' legs were acceptable, as was the burger. Side dishes were missing... they wanted to charge extra... in short, we ended up not ordering dessert. The bill was half empty... we told them so... they ended up offering us drinks for free... why not, but frankly, we have no desire to go back. Clearly, they are understaffed; the menu is too extensive to deliver on all the promises made on the plate. It's worth noting that there was a very pleasant jazz band, which was a nice surprise. I'm sure these comments don't surprise you, but I want them to be constructive. The ingredients seem to be of good quality, and the recipes are unusual, so it wouldn't take much to turn things around. I wish you good luck!

A very pleasant setting in spring, well located, and quiet.

Inn nestled in the heart of the forest, warm welcome and atmosphere. Excellent meal for the price. I highly recommend it and will gladly return.

Fantastic establishment! Excellent value for money, very good and generous portions. The staff is very professional, welcoming, and attentive; they do everything they can to satisfy their customers. A warm, friendly, and unpretentious atmosphere. A great spirit, and you can have some wonderful musical encounters there—you don't find that everywhere. It won't appeal to everyone, as everyone is different; it caters to all tastes.

An authentic and welcoming establishment where it's great to meet up in a friendly atmosphere

A very good restaurant, just the way we like them, a very welcoming and friendly team, and top-notch cuisine. I highly recommend the baked egg, which is simply divine! We will definitely return.

It's rare, very rare to find restaurants that will accept you for lunch at 2:30 pm out of season. The food was excellent, the welcome was warm, and it was my first meal outside in 2026. I'll have to come back a little earlier to enjoy the concert on Sunday at noon!

Great evening last Thursday! Thanks to the organizers 😘 Good atmosphere, music, and a very nice setting 👍 I didn't try the food, but it looked delicious...

I discovered Restaurant Mireille Oasis during a short hike in the forest. It's an excellent place for lovers of traditional cuisine; I highly recommend the cuttlefish stew, one of the best in the area. The natural setting is pleasant and peaceful, perfect for a convivial moment. The portions are generous, and the service is warm, attentive, and professional. A truly wonderful experience that I wholeheartedly recommend.

An institution in the Olonne region where you feel at home and which I recommend
