I went in looking for a 'destination wedding' style dress in mind... and I ended up getting something completely different. Not saying that will happen to you, but I wouldn't base where I would look strictly on that.
I went to two places (in one day) and found my dress.
Ritche Bridal - TONS of dresses, all styles and designers. They had pretty much ever dress I asked about.
Beckers Bridal - Not quite as vast a selection as Ritche, but some other names, and their own designer name... ended up getting my dress here. They give a 10% off if you get alterations done elsewhere.. though I opted to get them done there and I'm glad I did as Rosa was a miracle worker.
Both places I found I had good service .. not pushy at all. Piece of advise though...no matter where you go, book on a week day if at all possible. I booked a Monday.. I had both places to myself!
