Candy carts and exhibitions go very well together. Aperitifs and drinks are very common at exhibitions. However, offering sweets is a novelty.
The candy carts can be the best friend of the exhibitions thanks to their easy transport. In them it is possible not only to limit ourselves to sweets but also to junk food.
This will allow your customers to go shopping and save the entrance fee that can be spent on sweets. It is a very practical option for a small economic position.
