Great idea! I am not a chef but a potential customer!
I think your website needs a section on "how it works" or FAQs?
Looking at your website, I immediately had the following questions:
e.g is there a minimum order price?
Can you order food from different chefs?
Is there a delivery cost?
Is the food delivered hot or cold?
Can you order single portions of different foods?
Does the food have to be eaten the same day?
Are you going to list the ingredients for people with allergies?
Would also be good to understand a bit more about the name humbsum? It is unusual.. Any reason for choosing it?
