We live a few blocks from Anthony's Pier 66 & Bell Street Diner and have gone several times. We always eat at the "Diner" (even though it is fancier than what I would call a diner), and have had a great experience every time.
We mostly go when we have guests in town because it is a great place to view the beautiful Seattle waterfront while you dine without spending a fortune. If you go during sunset - it is gorgeous. We have a 1 year old daughter and the staff is always very accommodating with her and I do not feel that it is too nice of a place to bring her. They do have high chairs available, but there are limited tables they can put them due to the restaurant layout. If you need a high chair, I would try to call ahead to make a reservation to shorten your wait.
We have always had very good service and I would say the food is good, not great, but good. If you have out of town guests, it is also nice because the diner menu has a variety of pricing options (a burger for around $8.50 and fresh seafood dishes for near $30.00). So if you are not sure how much your guests want to spend on dinner, Anthony's Diner is a great choice.
On one occasion, it was extremely busy and we had several problems. But the management and server handled all of the problems very well and even took several items off of our bill for the inconvenience. Because of the great way they handled the problems, I never hesitate going back. Give Anthony's Bell Street Diner a try and feel free to bring the little one.
