You can tell a good solid wood table from the doorway by the way light sits on it in the late afternoon, catching the grain instead of bouncing flat off a laminate top. A poor one, usually a veneer pretending otherwise, looks fine in photos and dead in person, no depth to it, like looking at a picture of wood instead of the thing itself. The real stuff has a kind of warmth even when it's plain.
It's not the right choice everywhere, though. If you move apartments every year or two, a solid wood dining table is a genuine commitment, heavy, awkward on stairs, and not something you want to be hauling down three flights every August. It's also the wrong pick if you want a table that stays pristine, because it won't. It dents, it scratches, it takes on the personality of whatever happens at it, and if that sounds romantic, know that it also means actual marks from actual keys and actual hot pans if you're careless. It clashes less with styles than with other wood tones in the same sightline, a honey oak table under a cherry sideboard will fight every time, so match the undertone of what's already in the room before you commit. Keep it away from direct radiator heat and away from a sliding glass door that bakes one end of it all summer, because wood moves with humidity and uneven heat will warp or crack it faster than almost anything else you own.
Over the years it ages in your favor, which is the whole case for it. The scratches dull into character, the color deepens a shade or two with light exposure, and a light sand and reoil every couple of years brings it back further than you'd expect for the effort involved. Use coasters when you remember, wipe spills before they sit, and resist the urge to cover it in a tablecloth all the time, since the wood wants a bit of air and light to keep its color even. A beeswax or oil finish is more forgiving long term than a hard lacquer, because you can touch it up in patches rather than refinishing the whole surface when one corner gets rough. In an ordinary room it sits easiest with linen or cotton, not too matched, mismatched dining chairs, a rug with some age or softness to it, and a lamp nearby rather than only overhead light, since solid wood looks its best in warm, low, slightly uneven light rather than anything too bright or too even.
