Use the seating area rather than food preparation or serving surfaces. Keep leaves and soil clear of plates, drinks, and walking routes. A coffee plant can tell an interesting botanical story, but it must have a suitable growing position rather than serving as a dimly lit label for the business.

Meaning, with a little thought.
Coffee foliage suggests conversation, a broad leaf gives structure, and trailing detail makes a softer edge. The plants remain ornamental and are not part of food production.
