This is definitely a new mom review.
I like this place, but I don't know if this restaurant really wants to be represented as the cool place to hang out with your little kids. My friend and I went to lunch today and we had great customer service from Jake and good food (Lobster Roll and Salad Special), while enjoying the weather on the patio. Our kids were with us and we we were lucky that there were only two kids since they had one highchair and one booster seat for the entire restaurant! I didn't get a good look inside so I don't know if space is an issue, but at least there was a diaper changing station in the women's restroom. So, I guess you should bring your child's own booster seat if you would like to dine here.
Bottom line: Good food, good service, and no one seemed to mind that I used a (clean) child's sock to make a hand puppet to amuse our kids. Just be willing to bring your own booster seat. Or at least one for your kid.
