I've never gone to Katz's and used a credit card. From reading the boards I know you can pay using a credit card near the end of the counter towards the back. I'm going there today with a 3 other folks. There's one person who will be paying for us on their card. I don't want to go to a table for wait service. for me part of the experience of going to Katz's is to order from the counter tipping the guy etc. What's the best way to do this so my friend can pay for all of us on his card & also tip the counter guy? thanks.
