It's an idea I've been contemplating myself so I did a search on "island with dining table", this was probably closest to what you described. I plan to convert our (never used) dining room at the front of Calif. bungalow into a bedroom and enlarge current kitchen into adjacent informal dining area so this option would work well (if I can get H to agree that is!)

Unfortunately there is no simple answer for the best dining table for your home as so much depends on your household, lifestyle, and dimensions of the available space. You need to think about who uses it, and how you entertain. If you have messy toddlers get something that is easy to keep clean, and is fairly robust. If you like to host large number of people for dinner maybe a table that can be extended. What is the size of your household? Do you usually eat at the breakfast bar? For materials and colours I would be looking at what you already have in your kitchen and family room as a starting point. Don't introduce new colours or new materials to the dining area that aren't already in the kitchen or family room. Your bar stools look good and work well with your kitchen. If you are happy with your bar stools I would use them as a starting point to see if you can source complementary dining chairs. Once you have sourced your dining chairs find a table that works with the chairs. Make sure that the dining chairs that you select are the right height for the table, and if you get dining chairs with arms (called carver chairs) that the arms fit under the table. The tops of tables are a fairly consistant height, but the clearance under the table depends on the materials, structure and the position of the table legs. The number of chairs that you can fit around a table will depend on the position of the table legs and the width of the dining chairs. Measure your available space carefully before looking at tables to ensure that you have adequate circulation space around the dining setting to access the external door. Make sure that there is enough room to get past a chair when somebody is sitting at it. Without knowing your household, or lifestyle, or the dimensions of the room I think a six person or possibly an eight person circular table would work well in the space, but this may not meet your needs (or fit). Best of luck with finding the best dining table, Dr Retro

Hi, I can see that there are a lot of rectangular / square shapes in the house already with the doorways, windows, kitchen island etc and the previous owners have obviously tried to break up the sharp lines by adding a round table - not a bad idea but the table and rug are just too small for the space! Its hard to tell from the photos how big the area really is but if you have the space a square table may work best or an oval table, there are already rectangular shapes in the kitchen and the sofa configuration, although maybe you are placing your sofas differently? Id also suggest chairs with a rounded shape to help soften and define the area.

for the banquette to be wide enough to lay on it would need to be at least as deep as a narrow single bed which makes it too wide to sit on comfortably without a very thick back rest or a giant pile of cushions to clutter up the space...why not consider a back and sideless freestanding daybed so the primary purpose is laying down and the sitting to dine is only short term and doesn't need a backrest ....this example or similar with taller legs would be a simple economical way to add the day bed feeling without expensive built ins and two along the window wall could look quite inviting with a simple throw and scatter cushion
