do you mean will you be able to see it from inside...? If so, Unlikely you will still be inside eating but if you are no promises of where you will be sitting.
If you mean will you be done in time to go back out to watch it...yes, you should be able to do it in time. But I will not say you will be able to get the best viewing spots!
