For dinning tables, if modern it should have a leaf option. Sweetest table I ever way was an antique Mission set for eight several years back, chairs included. Out of my justifiable price range, but DAMNN!!!!
For my home, a "cheap-arid equine" octaganal glass top table serves my needs. The glass is a bit scratched from the prior owner and his "habits", but I like it. Fits the space I have, confounds the cats when they "walk on air" and one day it will be an antique.
