Most of the alcohol deals happen during happy hour. So when a user selects alcohol but not happy hour, most of the alcohol choices are hidden.
Consider an indicator (alert?, popup?) when one or the other checkbox is chosen to alert the user to the fact that they may not see everything in either category unless both are checked.
Don't display the notification upon every click. Consider a mechanism that will alert the user only once per page refresh so that the user can be informed but not pestered. Possibly a cookie to preserve the single notification over refreshes.
