I've been here twice- the staff was very nice about helping me out and guiding me despite my novice questions. I'm new to this and have liked the products I've tried from here. I'll definitely be back.
I just wanted to write a quick review to say thanks. I'm a complete n00b and asked a bunch of dumb questions when I visited. They answered all of my questions and were super nice doing it. I don't live near the location but will visit again the next time I'm down in the Mission.
