It's a nice enough location I can see it being popular for events. I'm not sure what there normal rules are on reservations though. I'm sorry you were not able to go. Hopefully you found a nice place to go to for the anniversary dinner.
Should have called for table availability or made a reservation. Then it wouldn't have been an issue. Especially for such a special occasion. Getting upset about it being closed when you wanted it to be open isnt the fault of the resturant.
Not quite a question.
