Beautiful waitress, what should i do?

Almost every weekend i go to this awesome bar/grill by my house on the marina. There's this beautiful waitress that works there i see her every time I'm there. But ever since last night i can't get her out of my mind. Usually i think about her but get over it, but this time i just can't get her out of my mind and i have this strong feeling for her inside that telling me to do something about it. Any tips or ideas on what i should? I would love to eventually ask her out. I usually go with my family since we are all off doing are own thing during the week this is how we catch up. And some of the servers already recognize us.
