I'll offer a bit of advice. I've never owned a BBQ joint and have very little restaurant experience. In college I had two restaurant jobs:
1 - Brand new japanese place, I worked two shifts. Guy opened the place, hired a ton of kids, business was really slow and he laid off everyone who wasn't Asian. I'm not Asian. He did pay me at least.
2 - An italian place that was just a cover for a drug dealing business - I didn't know that when I took the job. The cook's parents owned the place, his girl friend complained about how he damaged her car the last time he 'did some runs' and he talked about how the cops were watching his house. I worked three shifts and we had only 1 customer that entire time, and their food was on the house, and no one was worried about the lack of business. I quit. I didn't want to be there the day SWAT came in through the windows. Lost money on that gig, I had to buy some clothes for the job and never got paid.
All that said, I did run my own business for about 6yrs building custom bicycle wheels, so I know a bit about running your own gig and social media marketing.
SOCIAL MEDIA is an amazing tool. Done right you can really increase your brand awareness, and it doesn't cost you much, if any, money to do so. That said, you need to be thoughtful with how you use it. Pictures and video are greater than just text. Don't post crappy pictures. Be careful with political posts. Make sure you're using the platform (facebook, instagram, twitter, etc) the way it's supposed to be used. For example, on Instagram used to (not sure if it's still the same as I don't use it anymore) you couldn't post links that were clickable, and users couldn't even copy a link, so if you put a link in the caption of a photo you were relying on the user to then go open their web browser and type the link in. Very, very, very few people will do that. I highly recommend
Jab, Jab, Jab, Right Hook by Gary V. If you know about Gary, you likely either love him or hate him. Personally, I really can't stand to listen to the guy, BUT, he is smart, and the book is a worthwhile read.
When talking with others about how their business is going, be a little skeptical. Many people will not be brutally honest with you if they're struggling, they tend to make things sound better than they really are.
Don't confuse busy with successful. Busy means you have a lot to do, success means you're making money. They're not necessarily the same thing.
Don't be afraid or ashamed or apologetic to charge a fair price for your goods. You need to charge enough to make it worth your time and effort, anything less just means you're working your ass off for nothing.
Don't compete with other businesses on price. You don't want to win a race to the bottom. Compete on quality, customer service, and experience.
Experience and customer service are HUGE. People can buy, whatever you're selling, at lots of other places. But people can only buy it from YOU and YOUR PLACE at your place. Highlight that. Sell yourself, highlight and sell your employees (
this is a great example IMO), and make people feel connected with you and your business. With my businesses, I wasn't selling anything people couldn't buy elsewhere. People bought from me because they wanted *me* to build their wheels, because I had a reputation for doing great work. They knew I would put them on the right components to fit them and their riding style and needs, and they knew the wheels would be built right and would hold up for years. They weren't just buying wheels, they were buying a piece of me. Give people a look behind the curtain, show them your passion and dedication to your craft. People connect with that.
Offering discounts, sales, etc needs to be done carefully, if at all. Done too much it lessens the value of your brand and goods, people get used to the lower prices and that's all they're willing to pay. I've gotten used to buying blue jeans on sale, therefore, I don't ever buy jeans unless they're on sale.
