In America, you have your Subways, your Firehouses, your Which Wiches............all of those are pretty good (well, Subway doesn't use fresh ingredients anymore so meh), and THEN there is MACADOS.
The variety is huge, any type of sandwich you probably want, they have. If they don't have what you're looking for, then go to the grocery store and buy a loaf and bread and some PB & J (just kidding, you can create your own sandwich, too).
I highly recommend getting the salsa con queso dip. It will put some fine mexican restaurants to shame.....it's that delicious.
Finally, top off your meal and stuff your face with one of their fabulous desserts. I recommend the Pop's Sundae Supreme. You won't be sorry, go ahead and order it, and the salsa con queso, and perhaps a sandwich or two. Matter of fact, order two, one to eat now, and one to stuff in your pocket for later. They're that good! Shout out to the Huttons, we always try to eat with them when we're in town ;o)
