Ask HN: Do you provide meals for your employees?

We are a small startup that is just about to incorporate. We are starting the process of bringing on a few employees for ~5 employees total. A big question we are trying to answer is whether or not to provide meals for employees, with the goal of course to increase productivity and time spent in office.

Does your startup provide meals? Which meals and how often? Have you found it to be successful and worth the cost?
