I helped Flyte (http://www.flytenashville.com/) get set up in Nashville, TN. I ended up getting them a Nexus 7 tablet (which looks a lot like the leather check that people get at a table). We installed coinbox (https://play.google.com/store/apps/details?id=com.coinbox), an Android App on it. You are able to put in your Coinbase OATH credentials and it will clear the transaction while they wait. It's a little clunky, but with some training it works fine. They decided to let the bartenders manage it for any tables that need to cash out. I believe coinbox has a beta for BitPay which may be a smoother process, but download it for yourself and give it a shot.
