This is a great way to get out and they sell everything from shoes, dresses, clothes, fabric, fruit, fish, etc. I mean if you can think it, it’s there and they have lots of stores to shop for anything else you might possibly want! Enjoy because this is a great way to spend the day! Also, look for Bagels and Beans which has great food!
