The traveling brunch festival known as BrunchCon is lining up food vendors and its dangerous open mimosa and bloody Mary bars in San Francisco this spring. $55 to $85 tickets to the one-morning-only bacchanal, held on March 25 at the San Francisco Armory, are now on sale. The event promises 30 vendors for “BRUNCHING + DRINKING SO HARD,” targeting the same demographic as the similarly named SantaCon.

But brunchers beware: New York food blog Grubstreet called the original BrunchCon event, held last year in Brooklyn’s Grand Prospect Hall, a “drunken hellscape:” Some angry customers complained about the allegedly oversold event, in which thousands packed into the venue and more were forced to wait outside in an all-too-typical brunch line.

For the SF event, part of a tour that includes, San Diego, Miami, and Los Angeles, 1,300 Facebook users have already indicated their attendance, and a frightening 21,000 have marked themselves as interested. Eater SF has reached out to event organizers for details on ticket sales and capacity.

Update 4:30 p.m. 1/26: A BrunchCon representative tells Eater SF that there are 2,500 tickets for sale in total, and about 1,800 of them have already been sold. The event is broken into two sessions so there’s never any more than 1,250 people inside at one time!” the representative emphasizes.

As for food, BrunchCon founder Sarelyn Radecke tells Hooodline she’s lined up vendors like popular Dogpatch brunch destination Serpentine, Firebrand Artisan Breads, and NOVY Restaurant — all located and vetted, she says, via Yelp. Doing her local market research, Radecke also observed that avocado toast is “huge” in SF, and will be well-represented at SF BrunchCon.

Better eat up if you’re planning to get your fill of Mimosas: “BrunchCon does have an open bar with drinks free-flowing, but if you are seen visibly intoxicated, you will be escorted out by one of our staff members,” organizers write, clearly speaking from experience.

SF’s BrunchCon will be held from 9 a.m. to 4 p.m. in the drill court at the Mission Armory. The military structure turned kinky porn studio has seen it all over the years, but this event could be its most debauched yet. Stay tuned!
