I've been to Willow a few times for various functions. The waiters and chefs at willow are always very willing to check, double check, triple check/ alleviate gluten fears about different dishes. For the most part I think the only real "con" to Willow is that it is located on a slightly "blind turn" in the road that can get backed up if traffic is heavy. Parking is vast both to either side of the restaurant and behind ( and I am a sucker for great parking). When you enter there appears to be a cute bar area ( that one day I will venture into). In general it looks like larger functions are done upstairs. It is pretty nice and posh upstairs.
The food itself is delicious. They were able to provide a gluten free greek salad with salad dressing and a steak and potato entree. For desert they had a rhubarb raspberry ice cream with fresh raspberries.
Its a great time, the staff doesn't pressure you to leave and the food is tasty. I will be coming back.
