As a restaurant owner myself, i feel that if you can show me how you can save money, improve productivity , improve marketing and also able to finance the Pos then I am interested. Since this is a large investment , restaurant owners are usually not looking to upgrade unless their system is out of date. Not sure what you mean by Is it too high end?
I think a big part is how you present the system. Besides the benefits of saving money and being more productive, I would really try to hit their deeper feelings. As someone who used to own a coffee shop, I would have loved if someone came in and educated me on the stuff I didn't know. How their system could reduce stress and make things more organized so I could spend less time doing the stuff I hated and spend more time with my family. Know what I mean? It really comes down to getting into your prospects shoes and finding out what they are really wanting. If you can make them feel like you understand them, they will be interested in what you have to say.
Successful case studies that address the pain points of businesses are always a solid approach. If you don't have a case study then you should consider testing your concept prior to developing it. Since restaurants run on relatively thin margins consider a subscription model or monthly payments to make the invest affordable. Good luck!
Ask yourself what would your restaurant cafe owner want? How do your tools solve a problem they have? If you package your resources so they solve a problem, ie lead generation, forecasting, just in time printing (cost saving) then you might start to get their attention.
Definitely need some case studies and testimonials from other happy customers. With Ipads and square software a lot of restaurants or retail stores don't use traditional POS systems anymore so you have to differentiate yourself from them.
Focus on how using the predictions and analytics can help your prospects save time and money
