The website for this colorful-terrace is based in the same bright magenta, purple, red that you see here. There were few patrons enjoying this sunny morning, but I would imagine a full terrace for déjeuner would be expected. It sits at the corner of Rue Paul Cezanne, and is only a stone's throw from Avenue Myron Herrick.
Herrick (1854-1929) was the Governor of Ohio and subsequently the American Ambassador to France. It is interesting that he is the only American Ambassador to have a street named after him in Paris. Herrick was the ambassador who hosted Charles Lindbergh in Paris after his successful New York to Paris Atlantic crossing in 1927.
