About Diablo Burger

Diablo Burger is excited to announce the return of their full regular menu! They feature 6oz of 100% local grass-fed and hormone and antibiotic free beef patties and it's making them famous! Each burger is made with 6 ounces of 100% local, open-range, antibiotic and growth hormone-free beef from Diablo Trust Ranch, charcoal-grilled on an English muffin and served with seasonal greens, tomatoes, pickles and their DB Frites. However, since opening in 2009 Diablo Burger has learned that that a well-done burger isn't for everyone. That's why they cook all their burgers to order, literally they measure the temperature of each one so let them know which temperature you prefer!
