I've had offsite food before and onsite food. Yes onsite food comes with queues, but meet up while working + queue + eat still beats the hell out of travel + meet up while waiting + travel + queue + eat + travel.

In my experience, onsite food (free or cheap) is often 30 to 45 minutes. Offsite food starts at 45 minutes and can be occasionally up to two hours and this is mostly out of your control.

I imagine this is pretty dependent on the exact area you work in though.
