Great hotdogs and as many toppings as you can fit on the hotdog for only $5. They have 50 different toppings. Some of them are pretty interesting like coco puffs, hot fries, peanut butter, etc. I definitely recommend getting the Vegan Sausage. It tastes just like an Italian Sausage.
Additionally they have tater tots or fries for $3 with as many toppings as you can fit on them. The fries and tots themselves were crispy and potatoy.
When we visited Happy Dog, the place was currently reserved by some senior citizen organization. There were still a few tables left for walk-ins. It's nice to see that no matter what age you are you still enjoy a good hot dog at a local bar.
