I visited the Yellow Door Bistro for a work function before the holidays. For a hotel restaurant, I would say Yellow Door is above average. Great ambience and decor.
Many of my colleagues had the buffet and seemed to enjoy it. Due to dietary restrictions, there wasn't too much on the buffet I could enjoy, so I opted for the prosciutto omelette with egg whites. Personally, I was underwhelmed. I found the food to be greasy and heavy. I think that the omelette needed some more veggies, or at least the option to build your own.
This would be a great spot to go with out-of-town guests, and I'd be interested in eating dinner there. But I personally would not go back for breakfast.
