I look for a place with a nine or above on the Joel Test. I will even ask the manager for their Joel test score or ask if I can help them get it there.

Definitely two monitors or more per developer. Great windows and ventilation. Fish tanks in foyers are generally good for Feng Shui (Chinese art of design). The catch is they must be clean and colorful so that they can bring good energy to a place which will help the people feel good and the business will generally benefit.
