Think one night in Bangkok and the world’s your oyster? Try downtown this Saturday when Castle Builder throws its first interactive multimedia private party, Sweet Siamese. Nab a ticket online and wait for e-mailed instructions covering what to wear and where you’ll find the warehouse space that’s gotten an art nouveau/Secret Garden makeover for the evening. Along with savories and sweets passed throughout the night and the option of indulging in infused-vodka cocktails and more at the bar, expect the unexpected: an active tea party installation; ballerina on a shelf; a little burlesque; photography; video projections; and an array of musical acts, from a saxophonist to singing sirens chained to a piano by a heartless madame (ah, that explains it). It’s a show with everything but Yul Brenner. Tickets available online at castlebuilderproductions.com. Location information will be e-mailed to you after ticket purchase. Of course, you’re fashionably late! There’s still time to catch The Dossier.
