my favorite local joint is Two Hippies Magic Mushroom Burgers
$5 gets you a good-sized hand-formed patty, fries with house-made seasoning, and a 12oz can of pop, all brown bagged and greasy and absolutely decadent
premium burger meal deals are $6 and $7, including things like teriyaki, blue-cheese, southwest burgers, etc
