Obsessive about ingredients, Roam serves burgers of beef, bison and turkey, all locally grown and sustainably farmed. For classics, stick to juicy grass-fed beef served on a fresh-baked bun with house-made pickles. Don't ask for Coke: Roam makes its own organic sodas, plus stellar milkshakes with ice cream from Sonoma. There's also a branch on Fillmore St.
