For example, you may or may not have finally got this done, got it shipped, all those things are great. But your workflow and marketing are meant for tables. This is now dead on arrival.
Second perspective as a restauranteur: $219/mo is crazy expensive. I pay $300/mo to Revel and $180/mo to Clover for two different types of businesses.
With the $300/mo to Revel they process thousands a day and I have 24/7 phone support that within 2 min a live human handles my problems.
With the $180/mo to Clover they process hundreds a day and I have an easy to use, to easy to service system that I can hack into and custom build Android apps to do whatever I want.
Your $219/mo don't come close to delivering value like that.
Sorry.
