Taking baby out to dinner??

So my little one is 28 days old. We have left house to go on short walks outside in his front body carrier, and to doctors appointments but that’s it. (Dad has done all the shopping). I’m wondering when we can go out to eat and take the baby? I plan yo not letting strangers touch him. But given its cold outside and RSV season is ramping up, I’m just curious what others are doing? I hear some go out to eat first week with their baby, and some wait until the baby is 8 weeks old. What is everyone doing?
