Sunny Side Cup is a coffee shop located in downtown Quahog, Rhode Island. It's gone through numerous name changes over the years, with each name based around a coffee-related pun.
In "Lifeguard Meg", Brian and Stewie earn ownership of the place after winning a pun contest, following the previous owner's cancellation over an improperly capitalized tweet. However, they fail to prepare their workplace properly and risk losing business, though Brian saves face by stealing Folgers from next door. This is revealed to the customers by Principal Shepherd, which impresses the youth. However, one customer cancels Brian and Stewie over the former's social media activity, prompting them to hand ownership over to Shepherd.
