“Starbucks” (starting with a capital “S” and with the “s” at the end) is a very popular chain of coffee cafes. There are thousands of them across the US, and recently they have expanded to other countries. The sentence as written has errors. It should read: Currently, Starbucks is one of the stores that are very crowded. People like to go there to hang out with friends and to relax.
