I ordered the Reuben sandwich with a side of their soup of the day, tomato. The sandwich arrived in 10 minutes, and the first thing I noticed was that the corned beef was in generous slices and tasted very tender. The Swiss cheese did its job well of holding the ingredients from sliding around. The biggest disappointment in the sandwich was that the sauerkraut and dressing, which tasted so awesome in the first bites of each half of the sandwich, didn't quite make it to the edges of the sandwich. Everything dried out as you got closer to the crust, where it was just corned beef and crust.
The sauerkraut and Thousand Island did combine pleasantly with the hearty-tasting corned beef. The bread was very good. It was a little crunchy, but not overly so. The sandwich could maybe have used a little more of the Thousand Island dressing, or else everything could have just been spread a little more fully throughout. The sauerkraut had a bit of a sweet tang to it, which worked well with the beef.
Overall it was a very good sandwich and I would recommend it.
The tomato soup that I had for my side item was very rich and delicious. It reminded me of a marinara sauce that you might dip breadsticks into, although it was creamier than that. The Black Bear Diner had so much good looking food on the menu, and I assume that all of their menu items would taste as good as the things that we ordered. It would take a while to get through all of the yummy looking things they offer.
