Not convinced by real time updating beer menus. I was in The Pony Bar in New York which had a very impressive looking real time list on screens behind the bar. However when I ordered, my first two picks were already off. Great in theory, but in a busy bar the staff have to make time to update it, not always possible.
I also worry that one of these days my phone battery will run out and I suddenly will no longer be able know what's on the menu, pay for a beer or get a taxi home <!-- s;) --><img src="{SMILIES_PATH}/icon_wink.gif" alt="
