This place can and will get mobbed especially on the weekends. If you plan on being a «walk-in» I suggest you arrive crazy early. Otherwise I suggest you make an appointment on the Quest website. They are VERY good with having your visit be very quick if you have an appointment. I really like and appreciate how appointments are handled promptly even when I arrive with a room full of people foaming at the mouth wondering why I’m being seen before them while they’ve been sitting there for an hour.
