I have 2 children (3 and 5) and both have been to Dr. Brian Yoshida a couple of times.
1) The facility is not what I consider kid-friendly. There are some books and a game station in the waiting area, but not much else. Inside where treatments are done is not very impressive either. I've been to much kid-friendlier pediatric dentists that have tv screens on the ceiling and more toys/books in the waiting area.
2) Chair-side manner is ok. He's fairly patient, but I could tell he was getting a little impatient when my 2.5 year old was crying during a cleaning. (I expected the dentist to stop since it was my son's first time there.)
3) They give a toy and treat at the end, which my kids like.
