Hello, are their diffrent vendors Every week? I'm looking for a spicfic people

No most of the vendors are regulars.

Is the market open on the weekend now...

I'd say all most every vendor is there weekly and I know many who have been there in the same spot for years

There is a variety of different vendors from apparel, books, electronics, shoes, food and ect... ect... I guarantee you will find something you want that you weren't looking for...
