I've been here a few times, and I've always been pleased. The service is prompt and welcoming, and the food always tastes pretty good. It's not the greatest sushi in the LA area, but I don't really think that's really their goal. Zono has a lot of creative rolls and fun combinations. My girlfriends and I like to go here for Girls Night, and we always, always get the crispy spicy tuna roll. I can't remember what it's called exactly, but it's #5 on the picture menu. It's so delicious, and so different! Also a fun novelty, two of the rolls have the same names as my friend and me, so we always get a laugh when we order "our" sushi.
Good prices for sushi! I've been here a few times now with friends and coworkers. It's not the best sushi I've had, but it's really affordable. If you go during lunch and do the lunch specials, you get a 5-piece sushi and miso soup to accompany your dish. I'm a fan of the Ocean's Quatro roll. Service can be slow. It's not the freshest sushi, but really, we're in Glendale here so I'll take what I can get. Parking is easy in the structure (free 90 minutes) and it's part of the backside of the Glendale Marketplace, next to the big HomeGoods store.
Whenever I feel like eating good Sushi in Glendale area, I always eat at Sushi Kai. It's kind of hidden so the place never gets crowded but the place serves good quality sushi and rolls for the price. Lunch is definitely a better deal than dinner since all lunch combos come with extra five nigiri sushi. There are so many lunch choices and all of them are under $15. My favorite is Basked salmon roll lunch ($13). You can order lunch menu till 4 p.m. There is a parking structure in front of the restaurant and it's free for 90 minutes.
