I'm visiting my younger sister in Seattle near the end of May, she's been there for nearly three years and this is my first time visiting her city. I wanted to take her out for dinner, and was looking for suggestions. Cost isn't really an issue, but I do think she would prefer a more casual atmosphere (and dress code). I live in NYC and work in the restaurant business, so I would love to experience not just great food, but something unique to the Seattle area. I'm also open to any ideas for breakfast or lunch! Thank you!
