Loved the atmosphere and the bartender/ waitress was excellent! 3 of us had the Reuben and it was very good. A little over grilled on the bun. We had the pub chips and they were burned to almost black...they should not have left the kitchen . I will go again but will not order the chips.

Stopped in for a sandwich and beer after disc golfing the Rock River course. Downtown location. Had the reuben. Corned beef is made in house. Fantastic. Also had the hamburger patty melt which was very good. Service excellent. Ate at the bar. There are old style wooden booths. Just a great find on a weekday afternoon.

Burger and ice cold beer for 20, what more could you ask for. 1st off the food was cooked to perfection, couldn't ask for anything else. I asked for a medium burger and it was right on the money. 2nd the service was incredible, 1 bartender and 1 cook ran the show. Had a nice amount of people roll in all at once and they handled it no problem. The atmosphere is great, playing some great music everyone can enjoy. It had a lot of room and a lot of games for everyone to enjoy. If I was a local I'd definitely frequent this bar, I'll definitely be back

Want good bar food?! Bismarck’s is by far our favorite stop in Watertown (behind Sake House of course ;)! With all specialty burgers at 11 and a side of tasty homemade “Main Street” chips, we often find ourselves here after a long week. Kick back, relax, enjoy full Wisconsin bar options, and stop at Bismarck’s!!

The gal that was our server was top notch. Best service I had in a restaurant in a long time. I believe her name was Jenny. I had a great fish fry and beer for a great price. I really like the older taverns. Historic on the inside. It is a lot bigger inside than I imagined and I did not feel cramped at all. I will be back again. My co- worker says Bismarck's has a great prime rib sandwich.

I came for the Friday fish fry. I don't eat a lot, but the price was very reasonable for all you can eat. The atmosphere is typical bar decor. Everything was clean and well maintained. Definitely worth a return visit.

Good burger, nice people. Will definitely go back

Great place! We overheard that Cassandra Martin Wagner is getting divorced.
