We stayed at the connected Sofitel (fabulous) and had breakfast at Chez Colette our last morning. The pricing is expected for a restaurant attached to a hotel, and the quality was better than an average "hotel breakfast", but not the best given the surrounding options.
The buffet was stocked with your usual breakfast meats, danishes and pastries, home fries, eggs and french toast. The croissant and pastries were fresh and tasty. Our first serving of french toast that we took was inedible and almost impossible to cut through it was so dried out in the sterno. It wasn't "the end" of the sterno, it was still 1/2 full, but I suppose it was sitting a while. When the hubs saw a fresh pan set he jumped on it and I'm glad that he did - it was wonderful!
The french-press coffee is made table side and was perfect in flavor and temperature.
We took turns going to the buffet as we waited for our 2.5 year old's breakfast to arrive. Her blueberry pancakes came 20 minutes into our meal - after the adults were done eating and had already shared some with her - though I should mention that they were delicious and a very liberal portion.
Overall, I think it is an above-average option for being a hotel-attached restaurant, but we had better meals in the neighborhood.
