The little strip mall on the corner of Montana and San Vicente in Brentwood seems to have run into a spot of trouble…  A while ago, diminutive coffee shop Brew-N-Beans gave up the ghost.  More recently, one of the Westside’s last few remaining carb palaces, Noah’s Bagels, quit their location there.  And now, it appears that smoothie experts Jamba Juice has closed down.  That leaves only scrappy Souplantation in the increasingly vacant mall.
