We ordered a medium-sized cup with Strawberry and Pistachio. The sizes are measured by weight, but the bottom of the cup was empty. When we told Marissa about it, she provided no explanation besides the obviousness of it being sized by weight. This wouldn't be a problem normally, but the customers next to us ordered the same size and they had a completely full cup.
The manager came out afterwards and fixed it, but don't expect much help from the gelato servers if there is an issue.
