Backside of a t-shirt for marketing of an ice cream shop

This is what a business in Poland was looking for in their t-shirt design

We need a nice backside of a t-shirt for our brand Shark Ice Cream. We are going to serve ice cream, and we need to design a back side of a t-shirt/jacket/top to inform customers where are we located. We would like there to be a logo (attached) and informations about location (Sopot, ul. Monte Cassino 60) together with words "zapraszamy" and "come & enjoy".
