For me it's hard to judge, since I spent the first 4 months of the pandemic caring for my elderly father. That took me away from my household, and I wound up spending money on his food and supplies (despite his attempts to pay for things).
During that time, I shifted a lot of my discretionary spending from dining out to ordering delivery, and my grocery bills also increased (also partly due to delivery fees, to limit contact). I also spent more money on games & other media. So overall, my food & entertainment budget were a wash.
However, my transit & travel budget dropped a lot, despite occasional longer trips home on weekends. So overall it's been a net positive.
It'll be interesting to see how things stack up now that I'm back at home with my SO. I suspect that it'll be even cheaper, since we're cooking more and sharing the grocery bills more evenly, etc.
