I know South Dakota is not on the Chowhound list, but if you are travelling I90 thru' Siuox Falls this summer check out these two spots. Minerva's downtown is a great clubbish looking place. Great food, good prices compared to larger cities. Open lunch and dinner, but not Sundays. Also Spezia on Western at 26 is wonderful. Nice feel to the place. Had Sunday brunch recently for 10.95!! A buffet set-up. Our foursome thought it was one of the best brunches we'd been had. Open regular hours, too. You won't be disappointed in either place. Same owners, by the way.
