1 and 3 year old at restaurant

How do keep your children entertained and somewhat still at restaurants?

I have two kids, 1 and 4, who are not the best at staying still for more than, you know, 30 seconds.. We usually don't eat at restaurants for said reason, but are going this weekend with a large group (who will not necessarily help with entertaining the kids).

Pretty please, hit me up with the best toys, activities etc you set up for your kids at the table, which etablert you to actually eat your food
