I was very pleased with my catering experience with Cosi. I have been a loyal customer on my own since I arrived in DC, and wish I would have thought about catering with them much sooner! They were very polite, and helpful in helping me submit my order order for 20+. The driver arrived 10 minutes early, and the customer service was exceptional as they reached out on various occasions to ensure my order was correct and that I was pleased with my service. I will definitely be ordering with Cosi again!
