Kitchen equipment is graded. Generally speaking, what kind of equipment to buy depends on the size of your store.
But it is nothing more than a complete set of equipment on the big stove, a complete set of equipment on the chopping board, a complete set of equipment for feeding, tableware and so on.
You can also go to a nearby restaurant!
Generally, people who sell kitchen equipment will recommend you to remind you when you buy it (but you can only use it as a reference, not all by what he says). I hope your business is prosperous.
