Please recommend: Cafe/Space to take office calls near Dinanath Mangeshkar Hospital

Hello Punekars, Please recommend: Cafe/Space to take office calls near Dinanath Mangeshkar Hospital. I need to spend almost half day at the hospital to take care of my mom. The cafeteria in the hospital is very noisy to take a call. I understand, its not my place to call it noisy, the DMH staff are doing really best, but I am looking for a quiet place to take office calls. Hence am looking for help. Please suggest.
