I've never eaten in a TB, ever....I have only used the drive-thru when I want something for the road and cheap. (but I would in the one above!)
I think the last time I went thru the drive thru was over a month ago....only to find out the $2 Chipotle Grilled Chicken Burrito had been axed.
Your expectations are too high if you think a $2-3 meal is going to taste like $6 meal somewhere else.
In the years that I have eaten their food...I've never once used one of their sauce packets. I don't like covering up the normal taste of food.
