the promenade in the heart of Brea, California. Often referred to as Birch Street. Basically, the only fucking thing to do in Brea if your under 18 and can't drink or party. Includes two movie theaters and various shops, and is very close to the mall. Kids swarm it on the weekend, the place to go, when your not at the mall or at school or something elsee unimportant.

Pretty much truee. Yeahh i live theree. :
BOY 1 "Sheeeeeet Sonn, You going to Birchh tonight?"
BOY 2 "Hell Yeahh. Got no where elsee to be."
-OR-
GIRL 1 "Heyy, wanna hang out this weekendd?"
GIRL 2 "Hmmm, Birchh?"
GIRL 1 "Suree, unless you wanna go to the mall."
