I have been going there for five years. I get compliments for men and women on my glasses. They have always provided good customer service. I was always helped right away, sometimes there was wait, but then I got to browse their selection. I understand now that they are under new management. I went in there today and they were falling over themselves to help me. Even though I had gotten satisfactory service previously, I was taken aback by their enthusiasm this time. Give them a shot!
