The living room is too small to hold a sofa
You can't have it both ways, to retain the integrity of the living room is not the location of the restaurant, and my house is the same. The only way to do that is to buy a collapsible table and take it out when you need it, usually in a free position. The design of the table is very much, many styles, you can choose a reasonable design, size suitable for your own home inside. I hope I can help you
Scenario 1Remove the kitchen wall and the balcony wallScenario twoAll made the tatami
Not only consider the wall from the sofa type, small ornament type sofa is good
