Yang's has a beautiful selection of flowers with decent prices to choose from. However, I went in asking for a custom bouquet within a budget and was denied. I was shown a pre-made bouquet that I didn't like and when I showed disinterest in it the lady walked away.
I ended up going next door and getting something from there.
If you know what you're looking for and don't need the help of other expertise then this is a great place.
