Gruner portland burger
The Grüner burger is truly a work of art.

 Those familiar with Portland's annual Time-Based Art Festival are accustomed to the stimulating exploration of visual, tactile, and aural sensations, and this year, TBA is dialing up the taste.

TBA Biergarten: This September 6th through 16th, the Portland Institute for Contemporary Art (PICA) is teaming up with Ecotrust and Edible Portland magazine to help top Portland chefs explore the artistic side of their culinary exploits. Every night, the teams behind PDX's hottest restaurants will take over the first-ever TBA outdoor kitchen at Washington High School's TBA Biergarten to explore the art in Oregon's freshest seasonal ingredients:

September 6, 10pm–2am: Boke Bowl
September 7, 7:30pm–2am: Grüner
September 8, 7:30pm–2am: The Woodsman Tavern
September 9, 10pm–2am: Artigiano
September 10–12, 7:30pm–2am: Via Tribunali
September 13, 10pm–2am: Portobello
September 14, 7:30pm–2am: Bunk Sandwiches
September 15, 7:30pm–2am: Nong’s Khao Man Gai

Entry to the TBA Biergarten is free, and original dishes will be served up at special festival prices before and after performances.

Blind-Tasting Bingo: For even more interactive food-based performance art, three chefs--Jason French (Ned Ludd), Naoko Tamura (Chef Naoko’s Bento Café), and Johanna Ware (Smallwares)--will each host a round of "blind-tasting bingo", offering the chance to try 15 small bites with closed eyes and open minds. The $25 tour of tastes will act as an intimate exploration behind each chef's unique flavor palate. Only 25 players will play per game each night (September 11th, 12th, and 14th) so reserve your spot today.

The Snack Office: Visitors to the TBA Snack Office will be able to indulge in $1 to $4 snacks that, in a perfect world, might replace the items more commonly found in vending machines. Inspired by Ecotrust's work with school districts, preschools, and child care centers to change the way Oregon's children look at their food, Snack Officers will highlight fresh dishes from the local bounty (like Fifty Licks Ice Cream or  ficoïde glaciale with rosemary honey from chef Abby Fammartino (Abby’s Table).
