Hotwire, In-Out, Capers, Coffee to a Tea, Easy Street, Cupcake Royale, Bikes & Brew, Infinity, Uptown (who are we forgetting?) have a new fellow member in the Junction coffee club: Starbucks. Didn’t know the franchise-mad mermaid had swum into that zone until we took an e-mail tipster’s advice and wandered into the newly remodeled Jefferson Square Safeway — and there, we found a Starbucks kiosk, just like the ones in the Roxbury Safeway and the Westwood Village QFC (which is just steps from the standalone WV Starbucks). At the very least, this is a reminder — as more grocery stores prepare to move into The Junction — that they’re more than grocery stores these days; most include banks and coffee stands, both already in abundant supply in the neighborhood.
