I've been to Kofusion several times. The interior is very modern and sleek. The entrees are pricey and portions are on the smaller side. The servers are friendly and attentive. The $1 sushi deals on Sundays and Mondays are worth it. My favorite is definitely the big roll; I believe it has egg, crabmeat, avocado and some other stuff, then tempura fried with some sort of sauce on top.
The best deal...and I'm kinda mad that I found out right before I graduated...is the lunch buffet! It's sucha great deal. Only weekdays though. The buffet is only around $10 and includes various entrees, such as curry chicken, fried fish croquettes, kimchi, soup, fried rice, noodles and three different types of sushi. The big roll is usually one of the three. Definitely keeps you full without breaking your wallet. :)
