I really enjoyed breakfast experience in Napa while staying at the Hyatt. I am generally not a big fan of a breakfast buffet, but when they make eggs to order I can be persuaded. This restaurant offered not only eggs cooked to order, but also a nice up-scale selection of cheeses and cold cuts, as a good European hotel would. Add a nice selection of fresh fruit and I am sold. Juices, coffee and tea are included in the buffet price ($20). Also available are expresso based drinks.
You can get a table inside, or have your breakfast on the patio, overlooking the lush pool area. In the morning, before it gets crowded, it was a truly relaxing experience.
If I could offer an opportunity for improvement it would be a better selection of breads.
