We have visited Tower Hill before and found it to be very enjoyable. Our visit this time was rather disappointing. Not only were there relatively few flowers in bloom, we chose a Wednesday evening specifically in order to wander the gardens and then enjoy dinner on the patio with live Jazz music. The setting was beautiful, and we were there long enough to view a lovely sunset. However, although we arrived only an hour after they started serving, they were already out of the swordfish, which was one of only two possible choices for my daughter who is vegetarian and also gluten sensitive. The sangria we ordered, and the salad and tofu tapas we finally selected ended up being just okay. The staff seemed unable to keep up, and one even mentioned that they still hadn't quite figured out how to fix their mistakes to better manage the flow of diners. Tower Hill has nice grounds and some good programs. My recommendation would be to visit the gardens in spring or early summer, and skip the restaurant.
