Amigo's off of Shawnee Dr and 47th St (the 635/35 nook in Kansas City, KS) is a wonderful mix'n'match restaurant.
Very popular with the neighborhood, they do $5.50 taco platters, and I must say from personal experience it is amazing! I never thought I would be so wonderfully, happily stuffed. Not to mention their super strong 2-for-1 margaritas, which I love!
It can be somewhat loud, so if there are many takers on this night, I'll reserve a table in the slightly more private room.
