HRC has a great guide on how companies rate on LGBT policies for their employees.  This runs the gamut of food to clothing.

Businesses are rated on a scale from 0 to 100, based on whether or not they have policies that support LGBT employees. These include anti-discrimination protections, domestic partner benefits, diversity training and transgender-inclusive benefits. This year we provided an unofficial score to businesses that have not, after repeated attempts, responded to the survey. An unofficial score is reflective of the information that HRC has been able to collect without help or input from a business. 

It’s a pretty good source for how to best spend your money if you’re pro LGBT.  The great thing is that it also comes as a smart phone application for free!
