The clinic is located in a shack erected from salvaged scrap, hooked up into the city's electrical grid. The main room has four large beds for up to eight recuperating patients and a modern table with seats for gatherings.
An Auto-Doc loaned from the city, an old, ornery model, sits in the room in the back, allowing the good doctor to perform even the most complex of procedures. Repairing the Auto-Doc is required for being able to reliably purchase healing (it will malfunction half the time) and avoid getting killed if one wants to gain combat implants.

Dr Andrew's clinic appears only in Fallout 2.
