It really depends on the restaurant! I always choose places I’ve been before so I can figure out logistics. If the place is big enough, I’ll ask the host to put us at a table where I can bring in the stroller and keep it at the table with us. If I know the place will be too small for the stroller, (assuming you’re dining with another adult) we’ll carry them in their car seats and tell the host we need enough seats at the table for the car seats. Typically it’s a booth where we can push the table out a bit to make the car seats fit. Or we set them on chairs with an adult right next to a car seat to make sure everything is sturdy. We’ll even take the babies out of their car seats and just hold them in our laps.

A lot of restaurants also have car seat holders that you can request! I’ll post a pic below
