I've mostly never liked restaurant hamburgers. Almost always too greasy for me. In an objective sense, Whataburger has got to be better than, say, McDonald's, but for my tastes, they're effectively equal, in that I don't want either one of them and both are likely to make me yak.
I've had many homemade hamburgers that I really liked, so it's not that I don't like hamburgers.
I've always claimed not to be a food snob, but on burgers I probably am.
