This place gets swamped with people regularly throughout the day because of its central location for all the hospitals and Case. I don't envy the jobs the people who work here have because when it gets busy customs can be unnecessarily rude to the staff. They do the best they can!
There isn't the most seating inside, but I usually use the Starbucks app for ordering my drink so I can avoid the line and get in and out quickly. They almost always have my drink done and sitting on the counter by the registers by the time I walk in (only about 3-5 minutes).
Overall, I don't think University Circle would function half as well as it barely does without this Starbucks here!
