Could this indicate a slowdown in the build-your-own pizza trend?  On a tip from a reader (Thanks Joey!), I went to check out what was going on at Pieology Pizzeria at 920 Broxton Ave.in Westwood Village.  As it turns out, it has closed down.  A note taped to the front door confirms it.  I’m a bit surprised by this.  Even in pizza saturated Westwood, it’s hard to comprehend why ever-popular Pieology, of all places, would pull up stakes.  I’ll keep watching to see what may develop…
