not sure about the green, not really screamin "Art Nouveau" to me. Maybe a different tone of Green! although its more of a contemporary green which maybe interesting!!... whats the decor of the Bistro gonna be like, if its a contemporary minimal/art nouveau cross then maybe... but thats gonna be a bastard for the interior decorator to pull off! if it isn't a cross!!! then change your green to another one!
oh.... i know its gonna be seen from a distance so the kerning in "utopique" need to be relaxed... but it maybe alittle too relaxed!....
