The folks above have given good thoughts.
My "destinations" would be about the barbecue meats,the dive type feel,and hopefully being able to see-as well as smell the cooking.
Have folks come to the counter to order,where they can see and smell the cookers being opened.
Naturally, dried pork and brisket go into the beans and you get a good serving.
Make a good potato salad with eggs and cooked bacon and acceptable slaw.Folks don't go to a "destination" for them.
One day a week[Sunday brunch?] leftover brisket and bakers are made into hash.
If your location is moderate priced,to allow you to serve your own hours,do lunch 11 AM until about two-or until you run out of the quality meat you will serve.
Dinner/supper from 4:30 until 7:30,or when the quality meats start to run out.
Seve meats to match your location.
Don't waste time with brisket in the SE.people won't order,cooks can't cook it,it doesn't hold well.Your supply is expensive.
It is pork country.Always pork shoulder,St Louis spares and loinbacks.
Cold weather maybe Brunswick stew/burgoo.
Do a chicken special Tuesday night,maybe all you can eat.
Hotdogs for kids,always.
Like Smokin' ,stuffed bakers go well anyplace.
Down South try it with a large sweet potato.
The Ridgewood,near Knoxville,TN uses hams for their bbq and does well.
Another near Williamsburg does whole cured hams ,slo smoked overnight and thin sliced.
In SW forget pork,except Spares.
Brisket,both ways.Smoked sausage and half chickens.
Cold weather,chili or pintos.
In any area do smoked turkey breasts one day a week.
Have good,fresh,condiments at all places.
Better to buy a top sauce and private label,than spend your time and money to make an average batch.
Unless you are skilled at desserts,have the best local baker make their best pie for everyday and alternate their 2nd,3rd,4th one variety each day.
If no good pies available,do a really good banana pudding.
For drinks always have the local regional favorite and a national cola and lemon-lime.
Same with beers.
A couple days a week offer one different item.
Could be mac n cheese.
Smoked corn in the husk with your rub in butter.
Could be a free deviled egg.
A small free ice cream.
Smoke wings and give one with every order.
An ABT with every order.on Tuesday
Don't get too much hand labor and overdo the cooker.
Give every diner a treat to go.
Homemade pralines,etc will be remembered.A small special cookie/fudge.
Here is Tuffy Stone's 2nd restaurant.He was a high end caterer with a lot of good ideas and then became a bbq cook.
We set up together a bunch at cookoffs and he is meticulous and does everything correct.
Here is an interqiew with him and check his main website for good ideas.[Q Barbeque]
