And dont forget, requesting a window seat doesnt guarantee you will get one. I wouldnt book dinner there for the main purpose of viewing the fireworks. We have eaten there twice and been nowhere near a window either time.
IMO,the restaurant was wonderful, we didnt care about the view and we werent even there during the fireworks. Its worth going to for the food itself. I know if I had my heart set on going for the fireworks and couldnt get a seat in that area, I would have been disappointed.
Good luck, I hope it works out for you.
