Burgers are all natural. Served on muffin instead of bun. Many choices of fixings, most spicy. Fires are fresh cut and seasoned. Small dining space with some seating outside. Burgers and fries are great, big and thick. I always let the cook choose the temperature of my burger as they know best. Medium was good. My partner got well done and it was just as good. I had the wrigley field. Servers are friendly and attentive. Good background music. Good burgers, good beer. Diablo Burger is a great place.
