Dropped in here during Phoenix Comicon and ended up coming back every day I was there. Location can hardly be beat. The wait staff was very friendly and helpful, probably one of the best parts of eating at Kokoro, actually. \n\nWhoever did their interior design really knew what they were doing. The place really has a great feel to it. \n\nI went with a friend, and we focused more on the dinner items and less on the sushi, so I can only speak to that. Katsudon was great. They added a bit of kick to it for a southwestern touch, which turned out really well. Their salmon teriyaki was great considering the price. My friend ordered their fried rice, and liked it so much that he kept ordering it three days in a row.  My friend also tried the tempura, which he said was a bit sub-par, but considering the price, well worth it. \n\nTheir \"dinner\" items come with miso soup and a salad as well. Salad is, to be honest, rather plain, but it's nice that they include it considering how inexpensive the dinner sets are. The miso soup was a bit salty for my taste, but still good. I would not recommend the spicy korean beef steak. In all honesty, the katsudon had more kick to it, and the flavor of the korean beef was fairly weak.\n\nOverall, eating here was a great experience. The food, on average, is a great deal. Prices are fairly low, especially considering their prime location in the heart of downtown. In general, you get more than you pay for here, but don't expect it to be the best in the city. \n\nFor good food on the cheap, in the heart of downtown Phoenix, I would  recommend Kokoro, although not necessarily my first choice.\n\nUpdate: Went back twice since I was in town again. Had some trouble with the service....during lunch the line was huge, and during dinner it was so packed that they were too busy to take my order. I ended up going somewhere else. Hopefully that's not a trend but...\n\nI should also comment on the chicken teriyaki. It really wasn't any good. Try ordering something else.
