The best dispensary I’ve ever been to. I’ve been to damn near every state that has a legal market. This is the best dispo I’ve ever been to hands down. A hash heads dream with every live rosin you can dream of. Owner made me feel like family from the moment I walked in.
Best shop there is. I’ve had the opportunity to visit shops from California to Oklahoma. Great Barrier Reefer AND the crew are the best, hands down. Knowledgeable, great products, community leaders/supporters and great conversation. They are in it for exactly the right reasons. Try them… and say goodbye to everyone else.
This is such an awesome shop for any and all my medicinal needs. The best brands, best prices, but above all the best service. Great team. 💚
I can't say enough good things about this place! All the budtenders hear are great. They make a real effort to remember you and the type of products you like. The flower is always top notch. Me and my wife have both made it our main spot. Highly recommend.
Beautiful buds and very nice people. I'm so excited to purchase this beautiful strain 😍 Can't wait to go back a try the others. I also picked up some oil for my dog so I'm hoping it helps with his seizures. If you're in the area I definitely recommend this place.
