From what I've read in the comments.. should I go there for dinner? I want to treat my sister and don't have a lot of money. Would I be waisting my money? Any advice would be greatly appreciated. Thank you.

do not waste your money, worst experience in my life.

If you want to impress her, take her to a local place like the Roadhouse Diner or Smoked. I may not be cheap, but will be well worth your money. Even the Burger or Pizza Bunker would be a good choice. If you 'had' to do a chain, I'd avoid Chili's... You're going to get a mediocre meal, and you're not going to save any money. Even Applebee's, or Dairy Queen would be a better choice.

From what I remember dinner for the two of us wasn't that expensive. Food good and staff was great. Been six months. Enjoy.

Not having a lot of money, well Chilly's is Both Expensive And The Great falls Chilly's Staff There Can Be Somewhat Intolerant.

Yes that would be a good place to take her.

Stick with the 2 can dine meals at the back of the menu and you will be fine

Depends on what you like. I think they post their menu on their website. We like their food, service and atmosphere and feel it's good value for the money.
