Being a Korean born American, I'm always looking for Korean restaurant and double bonus points if the restaurant is good. I have tried all the restaurants in Pittsburgh that proclaim they serve Korean food and have been mollified with mediocrity on many occasions. That is why I think think this is by far the best Korean restaurant in the 'burgh.
One of the best things I liked about Dasonii was that there was no pretense about it being a Chinese or Japanese restaurant that serves Korean food on the side. I understand that sometimes you need to cater to the unwashed masses but Korean food should be celebrated as it's own style that can stand by itself. Pittsburgh can be rather parochial at times, so imagine my surprise when I ordered the appetizers and I asked if the dumplings were Chinese dumplings (aka pot stickers) or Korean mandoo. The waitress told me that they were homemade mandoo and acted like I should expect nothing less!
The dining area was neat and clean without too many gawdy Asian decorations. The waitress was prompt and provided our table of seven (2 adults and 5 children) with great service. We had two Korean food virgins with us that were picky eaters so we stuck to the tried-and-true dishes that just about everyone likes. We ordered the fried mandoo, seafood and scallion pajan, dot sim bi bim bap, bulgoki, chicken bulgoki and jap chee. Everything was great! Not quite like mom used to make but certainly as good as food I had in Seoul. We will certainly be back to try the more "traditional" Korean dishes Dasonii has to offer.
