My wife and I made a trip to this establishment last week, I was having a real need for lots of protein.
The dining area is presents the gamut of impressions, sterile, warm, cozy, barnlike, all at once.
First, I've got to say that I don't want to be too friendly with my server. Just bring me what I order, don't try to form a relationship with me. I also have a real problem when the server addresses us as "guys". Pet peeve, but it gets me every time.
The salad bar was nice, nothing too special, although it was nice to have hearts of palm and really good quality sliced ham available. Also interesting was the pasta salad with large chunks of sweet pickles. Sweet pickles are a weakness of mine.
The soup bar was interesting, I was predicting that the black bean stew would be good and the Brazillian Goulash would be inestimately foul, I was 100% wrong. The goulash was wonderfully flavored and the black beans were ordinary and inhabited the same space as yesterday's leftover meat bits. The salsa was excellent with the goulash.
Following the soups the server brought clean plates and the gauchos strolled by with the grilled meats. I was looking forward to this (despite it's campy showyness) and found the meats to be nicely grilled. I especially enjoyed the lamb and spicey sausages. So many people turn up their noses at lamb, but it was nicely grilled and had the right combination of char and rareness.
The sides on the table were nothing to write home (or here) about, garlic mashed potatoes, and deep fried polenta meh. The coconut breaded bananas with honey were a nice ending touch to the protein fest.
I don't know that the food was good, and I think the Carnaval is a franchise. However, the meats were nicely grilled, the salad bar did have lettuce that was green (not the iceberg commonly found here on the great plains) and the goulash was tasty.
I did leave sated, and with my wallet empty.
Not a chowhound must visit, but a nice change from the usual in Sioux Falls.
