I haven't looked around too much for dining tables but I love the Kyoto Extension table from Room & Board. It's Asian antique meets mid-century modern. The chairs below I love for various reasons. Though I'm not typically into plastic anything, there are modern classic exceptions (see below). Perhaps there's a way to have one of each around my dining table, each chair would be it's own conversation piece and personality. It would be ideal to mix vintage with new too. One of these days...
The Tulip Chair by Eero Saarinen from Knoll Studio
The Eames Plastic Side Chair in White from Room&Board.
These chairs designed by Jason Lewis are absolutely gorgeous (and unbelievably expensive). Sigh.
These Tone chairs by Leif.designpark and De La Espada are works of art. Literally. Love them. I love them all together.
