It's supposed to give you a permanent basic oven, as I understand it, so you don't need to spend 50 meat on subsequent runs to do basic cooking. I haven't heard whether you also get a free basic shaker or if that, too, will be permanent. I expect that buying the items for fancy creation - the range and the cocktailcrafting kit - will continue to be 1000 meat expenses every run.
But we won't know for sure until he finishes rolling out the changes.
