We were here for dinner & got to try their Family Special Menu (Sundays only).
I had the Suyatem Plate ($28), which came w/ assorted nigiri sushi (few pieces of raw sushi, 2 rolls), assorted tempera (shrimp, zucchini, yam), chicken yakitori. All the specials came with salad, miso soup, rice & green tea ice cream. It was so filling ! I didn't find it particularly that out of this world amazing. It was nice, fresh but you can have this at other restaurants as well.
The Sunday specials were great! I don't think I would like it here on a regular day though. Stepping in, you can tell it's one of those pretentious places w/ nice decor & ambiance which simply means... we look authentic & can jack up prices & even more so since it's part of the Westin Prince Hotel.
They are having summerlicious at Katsura and those interested in the summerlicious menu sit in the teppanyaki area only.
Service was good. The waitresses wore kimonos and they were all very courteous.
Parking - ample & free! Make sure to give them your license plate number though.
Restaurant - Katsura is located to the right of the parking lot. You do not have to go inside the hotel first to access it. You could... but it would be a long walk :)
