I think I ordered the wrong thing considering there are lots of great reviews for Black Bear Diner. I met a business contact here for breakfast and the place was big and services was wonderful. I ordered the following:
Corned Beef and Hash ($10): it came with a side of "fresh watermelon", two over easy eggs and a biscuit. The Corned Beef was not from a can but it overcooked where the meat was crunchy and hard. The fresh watermelon was not fresh, it looked like it was sitting in a serving container. The biscuit was OK and the over easy eggs were good.
Polish Sausage Link ($4.50): The polish sausage had no flavor and it was super greasy.
There are other better breakfast places in Las Vegas so I will go there first before I go back to Black Bear Diner.
