Black Mesa Xen Pizza Easter Egg

Apparently there's pizza everywhere in Black Mesa but this is the one I found out of the map by accident. I accidentally got up there by launching myself before so here's how to get up there properly.
Am I the first person to find this one? Probably not

Where on Xen is this location? I threw pizza through portal but I can´t find it on the other side ... :(

It's about half an hour into Xen. You can see the location itself at around 31 minutes in this video: ua-cam.com/video/ozv8sOFYFpg/v-deo.html

looks like they may have patched this so that it's inaccessible
