This is really a 4.5 star rating. I came here for lunch with a friend on Saturday as we were in the mood for sushi. The restaurant is very small but decorated well. We were welcomed immediately and brought to one of the few remaining tables. As soon as we sat down we were given complimentary green tea, salad, and miso soup. We had not even opened the menus yet! So far they were starting off very well.
I ordered the shrimp sashimi ($8 - four pieces) and the cucumber roll ($3 - eight pieces). After ordering, we enjoyed our appetizers and both commented on how much we like our salads. Although it was the standard iceberg lettuce that you tend to get at Japanese restaurants, the dressing was different and was really good! Neither of us had the miso soup as we just do not enjoy it in general.
Our main dishes arrived quickly and we both commented on the size of the rolls - we were not expecting to receive eight pieces - and eight pieces that were stuffed well with a good rice to filling ratio! I like that they brought all four of our dishes at the same time (my friend's two rolls and my sashimi and cucumber roll); however, it was a bit odd that they split up our two orders and put one if each of our orders on two different plates. As in my shrimp was plated with one of my friend's rolls and my cucumber roll was plated with her other roll. My shrimp sashimi was very fresh and were good sized pieces.
The service was also very good and the wait staff were pleasant. WOW Sushi loses half of a star because I thought that $8 for four pieces of shrimp sashimi was a bit steep. They do have lunch specials, so the prices may not be as bad if you order one of those.
All in all this was a good experience and I will return. I would recommend WOW Sushi if you are looking for a quiet place for lunch in Yorkville where you will get good quality food and not pay astronomical prices.
