I absolutely LOVE d'Juice. The super friendly, helpful staff makes delicious smoothies and juices right in front of you from beautiful produce. It's located right by a yoga studio I go to sometimes, and I couldn't think of anything more refreshing to have after a workout! There are tables and chairs inside if you want to relax and enjoy your drink inside.
They even have a mobile juice cart that you can often find parked by Audobon park!
