This section has illegible color contrasts: If possible put all your style sheets into separate files (style.css etc.).
I can see that you've already fixed the checkboxes and they look good. Your top menu needs some attention too - the Home option is barely visible for me. You definitely need to look up how to enqueue your css and javascript files and how to apply styles properly - ugh, scratch that, just realised you're on Wix so you won't have much control there. <p class="font_7"><span style="font-family:wfont_ffea76_08c6d5bed2a64789985228232c163ab1,wf_08c6d5bed2a64789985228232,orig_arvo;">16.2g</span></p> Code (markup): Good luck with your venture, the example meals look amazing and it's a nice point of difference in the meal delivery niche.
As someone who is also looking to go in to the food delivery market I was interested in taking a look at your site, I dont want to be rude or offend but to be honest t really does look like its been put together by a 12YO! Scrap Wix and rebuild via Wordpress, you will end up with a much better looking site. Wix has way to many limitations to build anything nice. Go with Wordpress and spend some money on a theme and you'll end up with a great looking website that the search engines will find. As for the idea of oversized meals, I like that idea and would like to nominate my free tasting services! I have one hell of an opinion about most things and as such I'm more than happy to share!!!
