Send process to background and disown and exit the terminal (& and && operator clash in zsh)

I need to run a process in the background and then exit the current terminal. The following command results in error:

> google-chrome-stable &! && exit
zsh: parse error near '&&'

I've considered simply invoking 'google-chrome-stable &!' and checking the error code via an if statement, but hope to identify a simpler way to accomplish this.
