Pretty Cute Bus Boy??

so I went out to dinner at a local restaurant with my mom and her boyfriend, and our bus boy was very verryy cute. and close to my age. when I walked by him on my way to the bathroom, we caught each others eyes for a quick second and we both smiled. and whenever he took our plates he'd glance over at me and smile a little. even my mom noticed, but I couldn't really do anything about it then with my mom and her boyfriend being there and everything.

i was thinking about going to the restaurant with my friend. and if I do, what should I do or say to get his attention? or number? I'm not afraid of being forward with guys, I just get very nervous if I have to do it in front of people, or even my friends.

HELP! thanks in advance
