In the ravaged outback of Lusk, there are few eating establishments to be found. Triangle 4 Cafe seems to be the best choice if life has you travelling through the area en route to Mount Rushmore or some other more scenic destination.
We stopped into the Triangle 4 at high noon on Friday and were seated immediately. The interior is pretty big and have a good number of tables. The menu is similar to a diner, with some breakfast foods as well as sandwiches and other meals. I opted for the cheeseburger which came with fries or a salad. For starters, thank goodness it's independently owned because we were able to get medium hamburgers that actually had a touch of reddish pink in it! The burger was a pretty good size and had a decent taste. I went with the side of fries and they were good...crispy and hot, and not heavily salted.
The missus' had a fried fish sandwich which wasn't too bad...just your typical fried fish patty with some tartar sauce. She also enjoyed the fries.
In the end, as Yelp says my three stars say, it's A-OK. Not the best, but certainly far from the worst option in town. If you happen to find yourself in Lusk and your tummy starts rumbling, this is probably your best bet.
Been here a few times. Mostly for breakfast, or breakfast foods (I work nights).
Food is good, service is very good.
Omelets are the best thing I've had on the menu, and nothing is bad or meh.
There has only ever been one waitress on duty when I have been in there, so it may get a tad slow when busy. I personally have never had that issue.
They are open 5am-10pm not 5pm-10pm which is what Yelp has listed.
