I went here a while ago, but I wanted to post a review. Basically, they had a good selection, they let me try on a few dresses, they allowed you to take pictures, I didn't feel rushed AND they encouraged me to go home and think about my purchase overnight.
After having way too many experiences (myself and going with friends) where I felt like they were just pushing an immediate sale, it was a refreshing change to not feel incredibly pressured and was just able to have fun and feel like I made an informed decision about my dress.
They didn't do my alterations, so I can't speak to that, but they did press my dress for me and help me preserve it after the wedding, all which went very well.
