A coffee shop's design often reflects its neighborhood, whether it’s the quaint Paris-like charm in Savannah, Georgia, or the artsy grit of Miami’s Wynwood. Giving just as much attention as they do to the latte art (those dreamy designs etched into cappuccino or latte foam), proprietors are tapping into design trends with salvaged barn wood, ball-pendant lights, greenery, and hexagonal tiles. That fresh, modern white-wall look is in abundance, too, putting yesterday’s run-of-the-mill cafés with mismatched furnishings and dark colors to shame.
