Prime Rib at Trio Grille
Watch for our Prime Rib Specials!

TRIO offers Contemporary-American fare, featuring hand-crafted burgers, 10 beers on tap, a wide variety of craft beers and specialty drinks. Trio Grille is the perfect location in Marengo for working lunches or family-friendly dining.  Love sports? We have the largest TVs in the area for watching your favorite teams in a friendly environment. Or take one of our specialty drinks out to our relaxing patio.  Once you’ve finished eating, consider bowling a game on one of Glo-Bowl’s 16 lanes, or try your hand at video gaming, shuffleboard, pool or in the arcade. Need space for your next party or business event?  We have private rooms that seat up to 50 people.

Trio Grille has all the games on HD TV for you every night.  Don’t miss any of the action of your favorite team as you hang out with friends or family. If you ask nicely, we’ll even turn on golf.
