A zendo is a meditation hall or room used for Zen Buddhist practice. It is a dedicated space where practitioners gather for seated meditation (zazen) and other Zen rituals and ceremonies. The zendo typically has a simple and serene atmosphere to support focused meditation practice.
Zen is the meditation school of Buddhism. The primary practice in Zen Buddhism is zazen, which is a distinctive kind of meditation. Different Zen Buddhist traditions have slightly different ways of practicing. Depending upon the particular group, there are--in addition to zazen--liturgical practices involving chanting, prostrations, spiritual talks, and one-on-one interviews between teachers and their students. .

Good question. Zen Buddhism is the meditation school (variety) of Buddhism. Anyone who engages in zazen and the other practices of Zen Buddhism may be considered a Zen Buddhist.

Strictly speaking, therefore, there is no one to be a Zen Buddhist! .
There is no "Zen Buddha" there is "Zen Buddhism". Zen Buddhism is a school of Buddhist thought centered on meditation and the instantaneous awareness of the whole in any situation.
