Le Bistrot du Viaduc sur Lanvallay

A great little restaurant – a bouillon in a superb location overlooking the old port of Dinan. The owner is lovely and the service is quick. I highly recommend it.

A wonderful discovery right next to the Dinan viaduct! We received a very warm welcome, with genuine kindness and friendliness. We had a fantastic meal, with delicious and generous portions, all in a truly pleasant atmosphere. A huge thank you to the lovely and smiling waitress, as well as to the owner (a fake veterinarian), who was also very friendly. It's such a pleasure to find such welcoming people! We had a wonderful time and will definitely be back. We wholeheartedly recommend this place! 😍🍽️ Thanks again for this great experience and congratulations to the whole team! 👏 The Aveyron locals and the visually impaired person 😊

A lovely little place, especially the veranda. The meat was very good. Thank you so much!

If I could give this Bistro 10 stars I would. The staff went above and beyond. The view from the back section of the restaurant looking over Dinan is beautiful, especially at sunset! The restaurant itself is thoughtfully and beautifully decorated, food and wine were fantastic. Jean Christophe and his staff were an absolute delight! We hope to return to Dinan and will definitely return to “Gaston” if/when we do!

Had a great dinner, had a variety of French dishes that were absolutely fantastic. The wait staff was very friendly, efficient. Our French is terrible but they were very accommodating and helpful. Great views !

If you want to have a pleasant time, I recommend this place. The owner is super friendly and has a great sense of humor. The waitress is very pleasant. The food is very good and inexpensive.

It's quite pleasant, with a lovely overall view of the restaurant. The meat selection is incredibly tender and excellent; from the appetizer to the dessert, everything is top-notch, we really enjoyed it. The price is perfectly reasonable.

A great setting! The service was a tad slow for a restaurant that wasn't very full. The portions were a bit small. I'll go back to see if they improve!

Excellent food, friendly staff, unfortunately a cook was sick so there was a wait, but this was offset by the positives.

Exceptional service and top-notch cuisine. The waitstaff is incredibly attentive. The only downside was when, at the checkout, you encounter the chef with a foul face who doesn't even bother to say hello.
