Dear toneee,
Our plugin has no issue like this. Please check the FoodBook live demo on your mobile and provide us your feedback on the responsive issue.
Maybe it causes by the theme that you have used. Please provide your website URL to review the issue to fix.
Moreover, the cart table is fully responsive with the horizontal scrolling system with a horizontal scroll bar.
Furthermore, please create your own topic instead of posting a reply to someone else created posts. Because the post creator can feel bothered for getting unexpected notifications of every reply of his/her created post.
Best Regards,
ThemeLooks Support Team
