Can’t say i have, would you recommend them? I’m familiar with the name and I pass through that area about once a month. And love me a good dog with good sides [:)] 

 
Top Dog’s been a fixture in Berkeley for many years. They stuff all of their own dogs and sausages and have an excellent choice of types, from your basic Kosher-style dogs to Italian style calabrese, mango habanero and bockwurst. I think you’d like them.
