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.

Step back into an old saloon atmosphere with top-notch service and masterfully seasoned and grilled protein choices! My ribeye was amazing!! As was everything else! Don’t forget to order Tin Tators for your side dish!!

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.


Great Food

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.
