Best merchant solution for a bar

[Sword Smith]

Hi

I was hoping for some input on what you thought was the best merchant solution for a bar. Is it tablets with Mycellium installed, would it be better to use an online wallet like blockchain or are there other options where the bartender/employees can see that transactions are on their way to the wallet owned by the bar?

Should the bar use one or multiple addresses?

Sincerely,
Sword Smith

Ive bought a few coin kite terminals for the bars I'm integrating.
