How to acquire a business loan for startup cafe business?

Coming from the perspective of someone 10 years in VC, I would say very honestly that it is.. PRETTY RARE for a VC looking to invest in high-tech, scalable businesses to put money into a cafe.
Unless you plan to be something like a Luckin Coffee - and are able to demonstrate economies of scale or an interesting way of delivering a coffee experience to customers (preferably powered via tech). VCs HAVE invested in F&B businesses. For example, see Teabox. They are an online direct-to-consumer tea brand.
At this stage where you are at a stage even before pre-revenue, I would definitely look at angel investors who have experience in F&B. Find those that are able to bring contacts in the space, and other domain knowledge around rentals, customer service, supply chain, vendors etc.

If you have a good pitch, Venture Capitalist might want to invest.

But the number 1 question will always be, why should they invest in you, whereby they have other opportunities.

What makes you so different from the rest, that your cafe can succeed and not the others?
