Burritos have been on every taqueria's menu for decades. Yet somehow, there's always a customer ahead of us in line who needs the cashier to explain every variety in painstaking detail before placing their order.

In the interest of speeding up the line at our local Mexican joint, we thought we'd share the following Ultimate Guide to Burritos from the folks at Fairmont San Francisco. In it, you'll find detailed explanations for the most common burritos served in the States, along with their ingredients, the regions where they originated, and even a few fun facts about each.

Check out Fairmont's fun burrito guide below, then get back in line and make up your mind already. We're starving back here!
