Keystone Plaza is a busy shopping center with a variety of stores. Customers praise the friendly and helpful staff at the businesses, particularly the bike shop which has a large selection of bikes and equipment. However, the plaza is known for its limited parking, making it difficult to find a spot, especially during peak hours. Visitors also note that it can be challenging to turn left out of the plaza. Despite the parking challenges, many customers, including those frequenting Ban Thai restaurant, plan to return.
