Welcome to Pierre

This is Mary Etzkorn’s steakhouse. A few years after her divorce, Mary decided she wanted to start her own steakhouse. She didn’t have any money to finance it so she leased everything and used her credit cards and got it going. The name Mad Mary’s was her sister’s idea, who said, “You’ve got to name it Mad Mary’s because everybody’s going to know you’re mad at him.” She was referring to Mary’s now passed ex-husband since this was after their divorce. Today, they have waiters and waitresses who have worked there for many years, some eight years, others 15 and others even longer. Mad Mary’s Steakhouse has become a place for anyone and everyone. They have no dress code, which allows for everyone to come in, from truckers, to young families, to odd business travelers and even the governor. When asked about this, Mary said, “You can come in in a tuxedo or you can come right out of the field, and everybody feels comfortable. We have guys from a [livestock] sale barn come over …” So it goes without saying that Mad Mary’s Steakhouse is one of the spots to stop by when in Pierre.


Unbelievable Prime Rib

My favorite Prime Rib restaurant closed 20 plus years ago and I have been searching the US for the best Prime Rib sense. I FOUND IT AT MAD MARY’S STEAKHOUSE! The place is cool, staff is awesome and unbelievable Prime Rib. Didn’t want to take the last bite because then it would be all gone… 7 hour drive from MN for us and it’s worth it.

Stopped in here with a coworker while on a business trip. Steak was honestly one of the best steaks I’ve ever had at a restaurant. Would highly recommend if you are in Pierre.

My husband and I ate here on the recommendation of our Innkeeper. We were able to get sat right away at 6:30 on a Saturday. The place was busy and staff was efficient. Great fillet mignon and tasty deep fried shrimp. Price was reasonable but not cheap. Decor was fun to look at but not distracting. Would eat here again.

If your looking for the absolute best steak in the Dakota Plains, look no further than Mad Marys!!! Wow! Great service, food was prepared quick even with a packed house. Steak was incredible. Aged Midwest beef. Only the best!!

We visit Pierre once or twice yearly to see family. A meal (or two) at Mad Mary’s is mandatory during our stay. GREAT steaks and prime rib, tasty sides, great adult beverages including a decent beer selection. Can’t comment on the non-beef entrees because we invariably order the steak selections or prime rib which is always cooked to perfection and delicious. Old west decor, friendly, attentive staff, reasonable prices, just off Main Street with plenty of close parking.
