I really cannot say better things about Miko because I really love their food and they helped out our student organization with a major Asian food fundraiser. I can assure you though that my opinion about the food is unbiased.
I've gone to Miko twice now for their lunch buffet, and really like their offerings. They have sushi rolls (some raw and some fried), seaweed salad, miso soup, spicy soup, chap chae, sugar donuts, orange slices, salad with an Asian-style dressing, a really good sweet chicken akin to sweet and sour chicken, and either seafood, pork or chicken kalbi...all for under $14! The buffet runs from Monday through Saturday between 11:30 am - 2 pm. I particularly crave their chap chae.
They also do teppanyaki for weekday dinner, Saturday dinner and all of Sunday. I will have to go back for that.
