Ask HN: How would you be convinced to try out a new product as an enterprise?

I have launched my startup Poucher (http://poucherapp.com) and I am daring to ask a business question in Hacker News (considering most of them are related to technologies)

We are currently at the phase of speaking to restaurant owners. Our primary contact method is cold calls and later we proceed with a 20 skype chat (video call, if possible).

What I would like to ask on behalf of the business team is, if you were a restaurant owner (actually a potential customer in general) what would it take for you to be convinced to try out that product.

Questions

1)Would you have to see the sales person in a real meetup, or would you be convinced if the product was good enough? 2) Would cold call leave a negative impact on you?

Any answer would definitely broaden our vision and improve our approach methodology we apply to potential customers.
