_____a kitchen café
"_______a kitchen café ".. it will be a best matching tagline for your logo. Because your logo is already taking much space a very few space will be left for your tagline. If you'll add a long sentenced tagline full of words it will look lengthy and unattractive but after applying my tagline with underscore sign in it it'll definitely give your logo a classy look.
