Have you not tried Which Wich yet? Do it.
Buffalo chicken= hands down, my favorite sandwich ever in the world. I can't wait to get pregnant so I have an excuse to eat them every day.
I used to go to one in CO all the time and I really remembered loving it- when I found out one had opened by my work, it secured a regular spot on my lunch-break rotation until I realized maybe I shouldn't be eating sandwiches all week. I now prefer to hit up the AJ's next door for cheap tea and salad bar (healthier, obviously) but sometimes I wind up in the parking lot of AJ's only to instead go over to Which Wich... it's seriously delicious stuff. My husband love the Thanksgiving Turkey feast sandwich (probably has a cooler name than that) and my backup fave is the chicken pesto (be sure to add bacon.) Always- and I do mean ALWAYS- get your sandwich toasted.
Trust me. I'm a fattie who loves her some good sandwiches.
