South by Southwest is known for brand activations and pop-ups from big name chefs, but this year, the festival may have outdone itself. Chef Mads Refslund, co-founder of Noma, the Copenhagen restaurant ranked #1 in the world four times, is cooking at a pop-up in Austin during SXSW. The pop-up, a collaboration with Tigerspring Agency, will be held today through Wednesday from 8 p.m. to midnight. The meals will be served at the House of Scandinavia (340 E. Second St.) and hosted by Scandinavian Airlines. The menu is based on local Austin cuisine, as seen through the lens of Nordic cooking and sourced with organic wines and cocktails made with Nordic spirits. The two prix fixe menus range from $75 to $100 and reservations can be made by emailing email@example.com.
