Fluky's location on N. Western (6800N) has a drive-thru. It's a little convoluted as the drive-thru doesn't wrap around the building. Instead it wraps around the parking lot. Not sure if it was a later add-on, but it still gets the job done.
By the way, I wish I had read this topic last week, because I was driving home via Elston and needed a place to eat with a drive-thru (I had a sleeping baby in the car with me). Niko's was on the way home so I stopped by for a burger and fries. If not miserable, then indifferent service, overcooked fries and questionable meat on the burger adds up to something pretty close to it.
However, I will note that the one highlight of the meal was two slices of red tomato on the burger. They weren't very big - maybe 1 1/2 inches in diameter each - but they were ripe and juicy. It was a nice surprise to find a place like Niko's serving good tomatoes, rather than the dark pink tomatoes, often with whitish-green insides, that most burger/hot dog places serve.
