The Black Sheep is a new restaurant in Whitewater and my wife and I hope they can make a go of it. We ate there on a Friday night without reservations but were met quickly and cheerfully by the staff and were seated quickly. The philosophy of the restaurant's chef is to use as much local food, produce and beverages as possible, which we strongly support. The follow through to this idea was quite good.
The strong points of the restaurant are: good food, nice location across from a city park and lake, nice decorations, clean bathrooms and dining areas, friendly staff (hey, it's Wisconsin!). We did have some issues with the food: the lamb ravioli was tasty but the pasta was not fully cooked and tough; the salads were so so but since it's a bit early for fresh produce in our zone, this is understandable.
The negative points are just as Jarvis R stated: the wait staff are not well organized and trained and could be well served by having a dress code. We ordered drinks which came separately and only after a reminder. Same with bread and oil. The bartender needs training in mixed drinks.
All in all, we will certainly come back - there are many intriguing menu items and based on our experience, they will be worth trying. Whitewater needs more good restaurants like this and we hope The Black Sheep will do well.
