Very friendly staff, super down to earth. They make you feel so comfortable even before you enter the building. Easy ordering like 1,2,3. I'm not a big smoker but Victor helped me find some edibles that I'm hooked on now! This is one of my favorite stores now. I've brought friends and family here that are very satisfied with their products and customer service. Very clean inside and not bad decor. I would highly recommend them for your friendly neighborhood dispensary.
