Yes, the two annual Passport DC embassy open-house weekends -- Around the World on Saturday, and the European Union on May 11 -- are culturally enriching events that celebrate diplomacy. But the real reason everyone loves them so much is because if you play it right, the day is an all-you-can-eat buffet. With booze! Amid the company of alpacas!

There's often-delicious free ethnic food at many of the embassies if you're willing to wait in line for it, and know where to look (and veteran attendees know that a long line is usually a good indication of an embassy having food). To help you navigate, Passport DC plans to launch an mobile site on Saturday that will give you information about each embassy and country via QR codes.

But to help you plan your snacks, we got an early list of each embassy's plans for the day, which hints at where you'll be able to eat and drink. Here's a list of all of the embassies that mentioned food and/or drinks. Some embassies run out quickly, so if you want a taste, it's best to get an early start.

Embassy of Australia: "Sample vegemite and other popular Aussie treats..." Depending on your feelings about vegemite, this is one to either attend or avoid.
