This is the character for the name of a famous Shaanxi dish, biang biang mian (biang biang noodles).

From the wiki:

The noodles, touted as one of the “ten strange wonders of Shaanxi” (陝西十大怪), are described as being like a belt, due to their thickness and length.

Made up of 57 strokes, the Chinese character “biáng” is one of the most complex Chinese characters in contemporary usage, although the character is not found in modern dictionaries or even in the Kangxi dictionary. Due to the fact that the Chinese character for “biáng” cannot be entered into computers, phonetic substitutes like 棒棒麵 bàng bàng miàn or 梆梆麵 bāng bāng miàn are often used.

Many Shaanxi residents have to rely on poems/mnemonics to remember how the character is written.

See Dan Washburn’s entertaining post on his visit to Xi’an and his first experience with Shaanxi noodles.

The noodles do look pretty yummy though…

- cheers for the heads up “Daniel”!
