Get there 10 or 15 minutes early and put in a request for an outside table and say you are willing to wait. I had a 7:20 reservation there last year, got there around 7:10 and put in a request for an outside table. We were not seated until 8:00 but it worked out perfect, we were done eating our main course about 9:00 when the fireworks started. The waitress asked if we were planning to stay for the fireworks and timed it accordingly.
