Gertrude's has been on our list of places to get to on trips to AZ for years....we only just made it happen recently, and it was a lovely lunch experience. We sat outdoors in the patio (reservations recommended). Our waiter was a foodie and very helpful in describing the cocktail and craft beer selections, as well as steering toward the best menu options that would be tasty yet still leave room for a dessert.
While we waited for our reservation time, we were able to stroll through the gardens.
