Li'l Woody's is an independent burger restaurant located in Ballard, Capitol Hill, White Center, and South Lake Union. Their beef is grass fed from Painted Hills in Oregon. You can create your own burger, and they have meat substitutes and other sandwiches too. Their buns are handcrafted in Tacoma, WA, their fries are made from WA grown potatoes, and their shakes use Full Tilt ice cream.
Word of caution if you are sensitive to dairy and don't eat Canola oil:
they use butter to cook their meat in and Canola oil to cook their fries.
