Take your own carseat as no-one has them.  Also, be careful, most taxis don't have seat belts or just have lap belts so problem fitting the seats in safely.  Most restaurants are friendly towards children, but few have any facilities or menus for them and all were smoky.  Also, many people will kiss your children, or hand them animals and stuff - you need to have a view on how you feel about the hygiene aspect of that.  Despite that, a great, safe, friendly place.
