imo, subway has taken a turn for the worse lately. i hate their new breads and sauces, and i normally end up spending more there than i expect to.
burger king -is- truly king of the burger places. they always have pretty good service, a clean restaurant (around here anyway), and they don't go into retard coma when you ask them to "hold the onion" or whatever.
of course, if any place is SUCK, it's hardees. suck suck suck.
