This place was recommended to us by the optical department of Costco sunnyvale, as they do not do repair (anymore?).The place is very small but the person was friendly, fast and efficient: we went on a Saturday and for $30 he replaced a broken part of the frame holding the arm in an hour and an half. Since he did not have the material of the exact same color, he just painted the part he replace, the result looks great.Cash only.
