Attention, HQ2-ers: South Block’s acai bowls have arrived

Pressed juice and smoothie chain South Block — one of a dozen D.C.-area businesses chosen by Amazon for its retail space at its new HQ2 campus in Pentagon City — opened its new location over the weekend.
Owner Amir Mostafavi says it was an instant success, with more than 300 people lining up for smoothies and acai bowls before the doors opened.
The Arlington, Virginia, store is the 15th location for South Block, whose first store opened in Clarendon in 2011.
