Red Nails in Highland Park (St. Paul) does a great job and they are very affordable. They are in the same little strip mall as Punch Pizza. I took my almost 4 year old there with me on Mother's Day. They even added cute little embellishments (painted little flowers with sparkles) on her big toes for free. They have child size "hello kitty" (not actually hello kitty, but looks very similar) pedicure chairs. My daughter has been begging to go back. I think I've created a monster!
