Franklin's is an experience for sure. Gotta get there a couple hours early and wait in line to make sure there's some left. Some days are worse than others, although I actually haven't been in a couple years. We would bring chairs and coolers with booze and hang out in the parking lot for about 2 hours before they open.
Shortly before they open a staff member will walk through the line and get an approximation from everyone on how much meat they will be ordering. They would then put a sign up at a certain point in the line that tells people past it they might not get any meat. Every time I went the line was already well past that point when they came around. I think they open at 11 am and it's rare they are still serving at 1 pm.
I'll PM you my number so you can text me
