Even if you don't have a house or can't alter it (etc), I find it helpful to dream a bit. Dreams are important, because they create goals. Here, these are attainable physical goals that are conceivably possible to one day have. Even impossible dreams are useful and helpful, but these are different.
Impossible goals are always something to reach for, never gotten or forgotten, or found to be not all that great.
Possible goals may be gotten, forgotten, or found not that great, but they help us focus on a plan, if only to distract us from hardship, and hopefully, maybe, to make real one day.
Ultimately, we have issues, all of us. Compensating, dealing with, or dare we dream overcoming, those issues is an important thought, and we do that with tools. Tools can be mental (anger management, emotional intelligence, etc), physical (hand or machine tools, transportation, etc), or infrastructure (roads, pipes, farming, etc). Furniture is home infrastructure; it gives name, use, and function to the space we exist in. No house is a home without it, necessary, but not sufficient.
The furniture I enjoy enables greatest use and enjoyment of the room space. That space may be real in the world, or merely within your own mind, but is all the same yours, whatever the case.
That is meaningful by itself, but it raises many questions on tradition. Why have a "kitchen table?" Same question on "dining room table." It seems to dominate the room it is in, often naming that room as well. It is large, and economically unwieldy. There is indeed a solution, and the service restaurant industry has known it for years: the booth(s). The booth itself:
If you look for luxury, see this. It may not be the most technically practical, but it does work. Note the lack of back row wall seating. That said, it has a certain feature about it, as you are essentially seated upon leather couches with additional cushions. Depending upon length and dimensions, it could easily seat 4 to 6, even without seating by the wall. Were there seating by the wall, that would easily become 6 to 9.
Here we see the corner booth example, as simple seating; just add table. Though the color scheme is clearly commercial (those colors are said to make you order more food and be more hungry), it still has a certain structural quality. Though lacking storage under seat, one can see the sitter's comfort is the main concern. Perhaps this might be considered more stylish?
Taken by itself (without the neighboring units) that corner both could fit into the corner of many a smaller space. The seating width is 25 inches (and that may be reduced somewhat) Whereas the table is clearly not enormous either One could have seating for a large party in 40 or so square feet. If you consider 6 ft and some inches on each side of the square, then you're effectively saving space. Two of these back to back or two normal (non corner) booth units side to side (so the tables nearly connect except for a gap between them), would seat a large amount of people in a small amount of space quite nicely.
Now, of course, there is one glaring problem isn't there: individual seat access. With a dining room table and chair setup, you can individually leave your chair without asking anyone else to let you out. This isn't the case with the booth, as you'd have to ask the person sitting next to you to let you out. You may create breaks in the seating, essentially turning the benches of the booths into many chairs if this concern becomes too much.
Otherwise, the concept hinges upon basic polite humanity and .... O god, the concept is fatally flawed and doomed.
