It did work, I used it myself. A quick search shows others who had my experience. This was late 2019 for me. Here's the first link and the Google post on rolling out in summer 2019:

"Google Assistant just made a dinner reservation for me... I knew this was coming... but mind blown!" https://www.reddit.com/r/googlehome/comments/ezv3us/google_a...

"Now, you can use it on all Pixel phones in 43 U.S. states.

All it takes is a few seconds to tell your Assistant where you'd like to go. Just ask the Assistant on your phone, “Book a table for four people at [restaurant name] tomorrow night.” The Assistant will then call the restaurant to see if it can accommodate your request. Once your reservation is successfully made, you’ll receive a notification on your phone, an email update and a calendar invite so you don’t forget."
