Longtime staple Legal Seafoods has rolled out a new advertising campaign based on puns about marijuana (it’s now legal — get it?), although it will not be including the ingredient in its dishes. Restaurateur Tiffani Faison has built upon her popular portfolio of spots like Sweet Cheeks, Tiger Mama, and Fool’s Errand, recently opening Italian restaurant Orfano.
