Island Banquettes: Yay or Nay?

I've recently come across some photos of banquettes and that been beautifully integrated with kitchen islands.  This has brought to mind many preliminary design options that I've presented to clients in the past--and no one has ever chosen this option!  I think that when designed correctly, its a great way to squeeze in extra seating or a breakfast space, but I've never been able to get a client to embrace it and move forward.  So am I way off base in thinking these are clever and cool?  These images suggest otherwise.....there are some great designs out there!

This little bench sneaks in there so cleverly and quietly you hardly notice......which gives you the opportunity to drool over all of those lovely fabrics!

This island bench is part of a much larger, very creative floor plan, which you can see more of here.  The idea works beautifully in the space, as do the other great details like the transom windows, contemporary coffered ceiling, drum pendant shades, etc......

Not an island-style banquette, but I couldn't resist including this one because it's an excellent example of how to use built-in seating to enlarge and extend a galley kitchen.  I love the look of this space, and how the bench ties in so well with the rest of the cabinetry.  The dramatic mirror and ghost chair are great accents as well--very un-kitchen-like, which I love!

I saved my favorite for last--this kitchen has so many beautiful details in addition to that banquette!  I love how clean and serene this space feels, and how there is such a beautiful transition between the interior and exterior--those black architectural doors are stunning.  As for the island seating, it looks perfectly contemporary and anchors the space so well.  

So any thoughts?  Do these images sell you on the concept of integrated island seating?  I'm sold!
