Wall-to-Wall Studios recently launched two television advertisements for hotspots in Honolulu. The first, We Don't Do Sudoku, was created for Bambu Martini Bar, home of the $3.50 Martini and a never-ending happy hour.  The second, Ephemera, was created for Brasserie Du Vin, a rustic, unpretentious place where people gather to savor wines and eat hearty meals.
