There are many trade magazines that offer free subscriptions to industry professionals. Here are the ones we have found so far:
Restaurant and Institutions
Foodservice Equipment & Supplies (FE&S)
Nightclub & Bar
TradePub.com's collection of free "Food and Beverage" magazine subscriptions
Also, here is National Restaurant Association's directory of magazines. It is probable that you can get a discount or free subscription if you contact their subscription department. Most trade magazines make money off targeted advertising, not reader subscription fees, so they want the most qualified subscription base.
Update (06/09/06): Benjamin Christie was kind enough to mention this post on his site (BenjaminChristie.com) and also list "Australian culinary magazines which are available to the restaurant and culinary trade".
