I really liked this idea of having the walls of the coffee shop be the blackboard. However, Camino is a coffee shop with a wooden interior, so it wouldn't work for my brief, but it's definitely interesting. It's funky and different and eye catching.
Craft & Commerce Restaurant in San Diego awesome communal table. note the flywheel that raises and lowers the center steel beam that serves as placement for social plates. the chairs but in purple or yellow, black?
