  • My dogs love this place. They think they are human. They walk amongst people enjoying the views, smelling the food from restaurants and having fun times with the ducks. Now, back to the human... Great...  more »
  • Gosh i adore this place. There is so much to do and so many great restaurants in the area. I also love that the parking is free and we've never had any issues finding a space in one of the decks. Target is also here as well as barnes and noble.. two of my favorite places. My 9 year old also enjoys the paddle boats & park
  • Have you seen the new look? It's awesome, with several new additions including Dave's and Busters, Silver Dinner and Yard House. The deck around the lake is renovated to improve the appearance, comfort and appeals plus there is a purpose designed area to enjoy live music outside. I'm impressed.
