I had to use the bathroom before a long trip. I popped into various stores and eateries along the street, and I was disappointed with a "no" each time. Desperate, I stopped at Cosi and asked. Finally, a yes--no purchase necessary! On top of that, the bathroom was clean and smelled kind of nice.
Thank you, Cosi. I love your food, decor, and atmosphere!
(As thanks, I ended up buying something healthy.)
