Went in today because it was my birthday and I got a $10 off offer. Once I got there Joanne merge two separate accounts I had and told me I had lots of points. I was able to get lots of products to celebrate New year’s.

Pleasant atmosphere. Dorria made good recommendations. I think the place is great and I think she deserves five stars. The only reason I’m rating them four stars it’s because I think they need to rotate through their pre-rolls more. Today they had some new products but over the last month or two it was kind of the same go to items. Four star review was still a good review so please don’t be offended. Just offering constructive feedback.

George was the best! Super helpful and didn’t mind me asking a bunch of questions about the different types of flower, also gave us recommendations which we enjoyed. Awesome service, knowledgeable, and made shopping here a breeze :)
