Mirko has several locations. I've been to the Toco Hill location twice now. (Their HQ is at PDK airport---go figure.) Mirko is one of those casual, mid-priced but nice restaurants that has become popular since the Great Recession. They use design very well to set a mood. The room is very airy and the restaurant has an outdoor seating section.
They use a mix-and-match menu system: select your pasta and sauce, plus any side dishes you may want. I've been there twice now. On my first visit, I had the pesto. This time, I tried the Bolognese sauce. In both cases, I was more impressed by the pasta than the sauce. Their pasta is just right with that al dente bite. Their sauces were fine but none of the ingredients popped. I expected my pesto to feature the basil or the cheese a little more but nothing stood out. Similarly, neither the meat nor the tomatoes in the Bolognese sauce really wowwed me.
