"Caspers is a long time favorite. I ate them as a child and as an adult they haven't missed a beat!! They have great hot dogs and they keep it simple. They steam their buns and the hotdogs are just good. What i love is the mustard and tomatoes they add. It all flows! It may not look like much but they are worth a try! I guarantee you'll be back. They have a few seats but not much. I think they serve coca-cola products. I forgot to look."

"Caspers Hot Dogs offers classic hot dogs and chili cheese dogs in a nostalgic setting. Servers are very friendly and there is plenty of parking."

"This restaurant is a bit beyond its prime but it is a classic stop for a hot dog when in the area. The menu is limited, hot dogs, chili, tamales, chips, milk, fountain soft drinks. I can't believe in the area and not stop. Hot dogs burst with flavor when you bite into them. Traditionally served with mustard, relish, onion slice, tomato wedges and a dash of salt. Ketchup or cheese on request. Tasty and fast. Usually older female workers, you may be called ,"Honey" on occasion. Friendly to all and they know their regulars. Place is worn but very clean."

"This is my favorite hot dog place since I was a kid. The hot dog is always as good as I remember. The staff is fast and friendly. I have only tried the Casper Dog because thats what I like. They make it perfect everytime I go there."

"The chilli dogs were horrific. Chili's thad ne flavor tasted bad and eatable.It was cold. I cold the 0lace back and they didnt offer me a refund. KASPERS in Castro Valley is delicious.Your best pla e for a all Beef chill dog."
