Ever since I attended my architect friend's wedding in August (which featured an impressively long dinner table), I've been convinced that rectangular dining tables are the way to go. In theory, round tables are nice for large parties because they allow for all guests to see each other, but the expansive diameter may prevent guests from hearing each other. Oval tables may offer a happy medium. But if you're seated at the head of a rectangular table, you're probably missing out on some conversation, too. Ahh! Too many factors!
