Chicago: Happy hours are banned but Happy Days (generally Tuesdays) are not

England: In terms of minors MUCH is up to the license holder. Law allows for 16's and older to have a beer with a meal with parents. BUT a publican has the right to just disalow kids after certain hours, often as early at 6. Found that the latter is only a real issue in cities.. Country pubs rock in England.

Germany (Bavaria): No idea how the licensing works but was stunned how easy it was to get good beer anywhere.. ie you can be walking through a city park and BOOM there is a beer garden.. totally awesome.

Eurostar: Not sure the exact rules but saw a group set up a picnic spread with wine and food..

Australia: Pretty good but no such thing as growlers (an awesome idea at microbrewries in USA.. this may have changed)
