Once in awhile, I just take my daughter with me to Tulip’s Nails (in the same lot as Safeway, next to Papa Murphy’s, in the Junction) since they have a separate kids chair w/DVD player, open new tools to ensure they’re clean and unused, and have consistently done a great job. There’s a place along California Ave, near Than Brothers, that I’ve noticed has 3-4 kids chairs (they look like brightly colored teddy bears) near the front. But I can’t give a personal recommendation for them as I’ve never been.
