There has been a lot of mixed critics for Park, either preaching it or dismissing it and I think this variation is due to the different definition of a good sushi that people have. Park serves traditional japansese/south american fusion sushi a large selection of fresh fishes and delicate seasoning. Therefore, the odds of ingredients such as tempura shrimp or mayo are very slim.
The flavours are a lot more on the delicate side, bringing out the taste of the different fishes. During my visit, we ordered a deconstructed salad for 2, a selection of nigiri and a selection of sashimi. I was pleasantly surprised by the salad, which consisted of a large selection of vegetables and toppings as well as different sauces, each with their speciality - a definite must try!
I don't know enough about fishes to judge the sashimi slices, but the pairing of the different flavours with the different fishes on the nigiri was very good and interesting (it makes use of south american ingredients such as hot peppers).
Overall, I had a great experience here. The food is not cheap but you are paying for the quality and selection of fish (and the ambience of the place).
