When CJ, Ryder, Sweet and Big Smoke go to the Cluckin' Bell in the Grand Theft Auto San Andreas Mission "Drive Thru", Carl and Ryder both order number 9s while Sweet orders a number 6 (with extra dip).
Big Smoke surprisingly makes a much larger order consisting of two number 9s, a number 9 large, a number 6 (with extra dip), a number 7, two number 45s, (one with cheese), and a large soda.

Cluckin' Bell Serves primarily fried chicken and the menu items it has are shown in Grand Theft Auto San Andreas and Grand Theft Auto IV. Assuming the menu hasn't changed a lot in the 20 years between the games, we can extrapolate the contents of Smoke's order.
No where else in the game are the meals referred to by number other than this cut-scene.
Now there are a few things we can extrapolate from Big Smoke's order. A number 9 most likely contains fries and/or a drink to be upsizable, a number 6 comes with dip making it either nuggets/chickenballs or the salad meal, and a number 45 must either be or contain a burger to have cheese applied to it. I believe the number 6 is in fact the salad due to containing ranch

dressing as a dip, this explains how sweet originally got his nickname, he used to eat alot of candy but now he eats healthy, as in a number 6 or the salad meal. The number 9 is most likely the little peckers, while it could be the cluckin huge or big meal, i find it hard to believe that Ryder and Carl would eat that much food. The number 45 is most likely the fowlburger combo as it contains no drink, leading smoke to order an additional large soda to compensate, also it can have cheese. A number 7 is a true mystery, but given that when smoke is eating his food in the car he doesnt make any of the hallmark fried chicken eating sounds, it is most likely not the cluckin huge meal. We can extrapolate it is most likely the little clucker meal as that could contain nuggets. Given these facts, we can extrapolate that Big Smokes order contained 5 Regular Fries 1 Large Fries 4 Regular Sodas 2 Large Sodas 5 Burgers 1 Sixpack of nuggets 1
