2010's show I watched that I can't remember the name of

There was this one show about a group of teenagers who would hang out at this mall like place. It was only one story and colorful. They would do learning stuff and would always go to this one smoothie place where this guy they were friends with worked. The person I believed wore glasses, was a teennager, and was African American. I believe this show was on Sprout or PBS Kids, maybe Nick and was aired around the 2012 - 2014ish t was also live action. If anybody can help me find the name of this show or anything else that would be great! That is all I can remember but thanks in advance. It's also an American TV show.
