Wiener in Hand is a consession stand featured in Beach City Funland.
The business appears to sell hot dogs, hamburgers, popcorn, ice cream, and cupcakes. This is known due to signs surrounding the business. However, the ice cream and cupcakes could be instead sold by another business next door to Wiener in Hand as of the signs for them could also be counted for the menu for another business, however it was unspecified which one it was.
There are signs of what the menu of the business could have (such as a sign for ice cream, a sign for a hot dog, etc). There is also a fan, possibly a giant fridge, and possibly a giant window.
