Chik-Fil-A. Best nuggest ever.
But that’s cause I’m in the Northeast. If this were CA, then yeah - In N’ Out!
We have a chik-fil-a in The San Fernando Valley now.
I’ll take a spict with potato wedges and an Iced Tea.
While I think In-N-Out is quite tasty, it bends the rules stated in the OP. Since they cook everything to order it’s quite fresh, but I’ve never seen an In-N-Out get anywhere close to filling an order in 5-7 minutes. Usually more like 15-20.
I’ve never timed it. But every time I go there, I think it’ll be a little while and start to read a book or something, and some young thing dashes up to my window with my food, and I think, “Already!?!!”
Now I’m trying to think of a good reason to go to Akron…
15-20? OK, I’ve only been to about twenty or thirty In-N-Outs in my life, but 5-10 minutes is about standard for my experience.
10 minutes would be pretty quick in mine. To be fair, I’ve never seen an uncrowded In-N-Out.
The occasional rare Firehouse Subs has a drive through, I’ll take that.
If the drive-thru is PACKED (often, 10+ cars in line), I will wait 15-20 minutes at In-N-Out. If only a few cars, certainly 5-7 minutes, maybe 5-10 minutes.

Can we go back in time before Wendy’s switched up their fries?
I’m surprised nobody else has said Rally’s. They definitely qualify: They’re pretty much nothing but drivethrough. Low prices, great burgers, great fries. What’s not to love?
In-N-Out
We have two in our neighborhood, and I’ve never waited more than 10 minutes ever. I would say average weight time at either one is 5 mins or so.
I’m surprised no one has said Swish Chalet yet… The one here has a drive-thru that’ll serve you well within your seven-minute maximum, and it’s relatively expensive, with damn good food.
I’ve never been to White Castle in my life. 
They don’t have 'em around here. So, I’d take the OP up on a trip to White Castle, assuming he’s throwing in a pair of plane tickets as well.
If not - Chick Fil A, for breakfast (ZOMG those chicken minis are pure crack deep-fried in heroin) but for shits and giggles, lets say it has to be on a Sunday morning.
A & W. Since this is pretend, I’ll go ahead and splurge on non-diet root beer (made in the store!) and the deep fried cheese to go with my chicken strip basket. I hope your pockets are deep because my whole family will be wanting root beer floats with their meals.
Steak & Shake has a drive through, though I’ve never used it. Closest one is 90 miles from here, though.
I’m stuck between Steak & Shake and Pollo Tropical. Steak & Shake is marginally better but I’m not sure if it counts as fast food as they cook a lot of your stuff to order, and IMO it doesn’t count as fast food unless they have a lot of pre-prepared stuff awaiting you (even if it is possible to circumvent this by special orders at a lot of places.)
Subway or Wendy’s…in Oahu, please.
Porky’s BBQ in either Memphis, TN or LR, AR.
Rack of ribs [dry], beans, slaw, biscuits.
Thank you!
Do you have an In-N-Out to yourself? Usual wait times are closer to 20 minutes for me. 
The one in Riverside? That one is always a long wait but other than that one, it’s 5-10 minutes for me. And when Phoenix got one, my students asked me if I had ever eaten at one:
Me: 
Then I asked the student if they had theirs animal style.
Him: 
Not often the teacher is cooler than the student.
