I love the built-in banquette attached to the island. I want a banquette in my next house. I love this idea, although I think I would do an l-shaped island with an rectangular/square table instead of a round one.
Interesting idea for kitchen and dining room. Island with a bench seat attached for the table. Might have to do something similar in my new place to save room for chairs. Under the bench seat could be storage for rarely used items.
