Don't be turned off by the chocolate-colored plastic chairs though. This, after all, is UP- no need to look for frills. Be happy for the good food (at oftentimes friendly prices, too), the good company (with the occassional theatre or film people walking in), and the feeling of being home.
The Chocolate Kiss Cafe is located on the G/F and the 2/F of the UP Bahay Alumni. Turn left from the University main entrance. It is right behind the UP Film Center. I believe they have opened a new shop on Roces, too.
No, I do not know the owners.
