Get the CB&J Burger. It's a 1/3 lb grass-fed beef patty covered in melted cheese, grilled onions and seasonal Mama's Preserves jelly on toasted ciabatta. (Jelly choices change with the seasons, we recommend you get whichever spicy pepper jelly is available at the time.) The Burger Bus is a converted yellow school bus that roams about town serving up juicy eats crafted from the finest local ingredients. The Burger Bus is one of Santa Barbara's oldest and most beloved food trucks. The easiest way to track them down is by checking their Twitter account, although there is a pretty accurate schedule on their website, too. Try getting your burger with a side order of yam fries or fried pickles!
