Sketching in restaurants can be a real challenge: people move around a lot, and food and dining companions expect some attention as well. I usually end up sketching quickly, and always add the watercolor later on.
The last sketch is at Venezia, an Italian restaurant with a unique decor. The walls are painted to make the space look like an outdoor cafe in Venice, and terraces, pigeons (fake, not real!), a fountain and a real laundry line complete the look.
The laundry is changed regularly to match the season: Santa suits, bathing suits, long johns, for example, and even lingerie at Valentines Day. I always get a kick out of that.
