Kasper's Hot Dogs - Castro Valley

The service was wonderful. I don't typically eat hot dogs and it was my first time there. I'll definitely be back.

Tried and true, always consistent yummy dogs and friendly service! Thank you!

The Castro Valley location has the BEST service ever!

We received a warm and genuine welcome from Carmin, who provided outstanding service with a smile. The hot dog was incredible and brought back memories of the old days. Carmin prepared it perfectly and expressed her gratitude for our visit, which was so refreshing. We will definitely be returning!

I visited from out of town specifically to enjoy their hot dogs. They have that nostalgic flavor reminiscent of school lunches that I remember so well. It's a craving I have to satisfy every now and then! The staff is friendly and professional.
