4 stars for the atmosphere. There are not many places in Pittsburgh to dine along the water and the outdoor seating at Redfin Blues is fantastic-huge outdoor deck with lots of tables under umbrellas. It was the perfect venture for Sunday Funday and I don't know why I have never been here before-well it is pretty hidden. They have a large parking lot and the outdoor seating was seat yourself.  It wasn't crowded so the service was fine but I could see on a busy Friday or Saturday the service would be less than stellar. We drank a beer (they only have bottled beers) and sat by the river to watch the boats go by.  The beers are pricy as our Curious Traveler Shandy was $6.50 each but it was a perfect drink for a hot day!  The menu is mostly seafood and pricey-the buffalo shrip where you only get 5 was $11.  It was only 3pm so we went with an appetizer of cheese fries with bacon and ranch-delicious and how could you go wrong! The fries had a tasty seasoning on them.
