Surviving dinner out with a baby?!?

My daughter will be 10 weeks on Sunday. We have been out with her with other family members but we haven’t been out just me, my husband and her. I want to go out for dinner but my husband is worried she starts screaming while we are out. She is too small for a highchair so she would need to be held or in her pram. Anyone got any advice, stories or tips on what to do? Should we wait till she is a bit older and can sit in a highchair at the table with us? This is maybe a silly post but we do stress about her screaming when we go out
