Definitely get The Trio — too many good flavors to choose from to stop at The Duo. All the flavors I tried were great, but my favorite was beef, American Cheddar & bacon. Fries were awesome, too!
My fiancée took me there some weeks ago and the food was ok. It wasn't worth the pricing. Don't let me be the reason it stops you. Go and try them but if you're on a budget stay away.
