Charles Sorel, raised in France but with the Caribbean personality of his native Martinique, is providing a splash of sunlight at his breakfast-and-lunch spot in Corktown. His small space has bright yellow walls and bright yellow napkins. It’s accented in green and turquoise and is adorned with paintings in primary and other cheerful colors. Outdoors, a patio with raised beds for perennials has the beginnings of a greenhouse in which to raise tomatoes and herbs. Patrons may order crêpes, salads, sandwiches, cheese, ratatouille and coffee. Later this year, Sorel expects to be able to serve spirits as well.
