I like that there is so much customization available to make it as simple or complex of an interface you'd want! There are some features they need in order to be able to expand their product line beyond just tableside service.
If those options were implemented then this would easily become my favorite restaurant software because everything works well together seamlessly - from reservations through payments/credit card processing all with one platform. We've been using Table 37 since we opened our doors almost 4 years ago now (we're at 20+ locations) and have never had any issues when talking about customer experience during check out etc., nor do customers ever comment negatively regarding how easy things seem while utilizing them either.
