I would guess yes. It is a shopping district. Have fun!
The three answers above are excellent answers with accurate information, I would also like to add that on Saturday mornings there is also a farmers market at historic downtown Grapevine.
They are always open for business especially on holiday weekends where many local folks take their out of town guests to experience this laid back setting with lots to enjoy.
Ditto to above answer. This is a town. If you are going to eat, check the restaurant's web site for hours. If you are going to shop, most stores close in the late afternoon, so once again, check websites. Enjoy this wonderful community!
