I sent a message to one of their Atlanta locations asking about that in particular but got no reply. How did you find out they deliver in the Buford area? Would that same source tell where they deliver? That's the sort of information I'm trying to find out but don't know how to find it. And also why I'm asking people in a forum like this.
I'm going to answer your questions in reverse order.
The question you originally asked is part of a much larger question "Where do restaurants and roadfood places buy their food?". Fair question, since they don't teach this in elementary or high school, and especially if you never worked at a job where you had to buy wholesale from a distributor. The best primer I found is the Wikipedia entry for a foodservice distributor:https://en.wikipedia.org/...oodservice_distributor
One of the first foodservice distributors I bought from was what is now called Maines Food and Party Warehouse. I found them simply by passing their building up in Johnson City, NY about 30 years ago. Here, I found things that I saw in restaurants, but could not buy in local supermarkets. Things like Modified Food Starch, deep fat fryer cooking oils, and other things not for sale in local grocery stores and supermarkets. Maines has a detailed website discussing how these "cash and carry" stores work:https://www.mainesfood.net/about-us/
Maines was a comparatively small company back then. Their core foodservice distribution business grew tremendously, as described on their other website:https://www.maines.net/broadline/about-us
I think all of us on Roadfood have, at one time or another, found something at a roadfood place that we wished we could also have at home. Lets say the Sabrett natural casing frank found at places like Grey's Papaya in NYC. You CAN buy them at some ShopRite supermarkets in the Northeast. But once you leave the northeast, it gets hard. But Sabrett as a manufacturer sells to brokers nationwide. The only problem is that it is in pockets. So now if you can locate a nearby pocket, you can buy in bulk, possibly freeze some of them, and now have a Sabrett whenever you get the craving without having to travel to New York. On the New Jersey Hot Dog thread are many discussions on how to properly prepare Sabrett hot dogs.
In your case, you liked a breakfast sausage you found in Maine. The problem is that it is a private label brand, similar to the Great Value brand you find in Walmart. Worse, it is a private label brand belonging to a wholesaler who does not want to serve the retail market. If you had the cardboard box it came in and got the USDA plant number, you would know who actually manufactured it. But that is not a guarantee you could obtain it at retail. Sometimes an outfit as large as SYSCO will get a spice mixture exclusive to them. Besides, restaurants do not want to serve stuff that tastes exactly the same as food you buy at the supermarket and prepare at home. More sales that way. So, trying to buy a food item from a foodservice distributor is somewhat akin to planning a bank job.
I was a bit sloppy in claiming SYSCO delivered to Buford. Knowing the delivery radius of the average broadline foodservice warehouse, I took a look at a map and saw it looked like 50 miles down to Atlanta via I-85. A little like a carpenter determining by eye the length of a counter to be replaced. Just about every warehouse delivers out 50 miles.
I forgot to mention that SYSCO now has various lines of businesses, some in locations where they bought out the previous owners there. The one you want is in College Park. The one in Newnan is SYGMA. This is a dedicated delivery service for chain restaurants and the like.
Like I said in my earlier post, this is smash-and-grab. SYSCO Atlanta may not sell to you, and no local restaurant may buy from SYSCO the same sausage you had in Maine. Maybe another member has better information than I do. Good Luck.
