I've been to Duke's twice now for Meetups. This last time I was on a restrictive diet, so I want sure how great it would be. The server and the chef worked together to make substitutions fire all of my restricted foods with no trouble. And the server managed this while waiting on our party if 15!
I ended up with a delicious grilled salmon filet and steamed mixed veggies with a squeeze of lemon. It was fantastic!
