Update/change the CSS file

Hi

I want to change the colours and some styling of the template however the file path does not seem to exist and I am unable to find the correct CSS file to update. The file path says the following...
plugins/system/jch_optimize/assets/gz/30/6347c2bce76847663858bc75eb6319ce.css

however this does not appear to exist (Screen Shot prntscr.com/l9h3o7 )

I have tried the css files in the restaurant template folder but no joy.

Where do we find the correct files and file path?

Hi,
You have a plugin installed on your website i.e. JCHOptimize which is not developed by us. Please disable this plugin and make changes in vRestaurant CSS file which is available in vRestaurant component folder itself.
