Papi Queso has the best grilled cheese sandwiches in Charlotte. My personal favorites are the following:
Pig Mac - pulled pork, Mac and cheese, no onions
Pig Mac minus the onions and pulled pork, and then add Bacon. - yum!
Jalapeno Mac - this is a featured sandwich. It has a pepper jelly, Mac and cheese, jalapenos, sweet tomatoes and onions. Very nice combination. I took the onions off because Im not a fan of them. But for those onion lovers.... Keep them on. All of my friends love this sandwich with the onions. :)
