I reported on a lunch at Sushi Zone a while back and since then, I've been back 3 times for dinner. Each time, I've focused on their appetizer menu. Every day between 5-6:30 pm, appetizers, beer, and wine are half off. With the normal price range of $3-8 for appetizers, these prices are great! On Monday, 4 of us ordered 10 appetizers, 3 large Sapporos, and 2 sushi rolls (full price) for $70 including tax and tip.
I've tried maybe half of their 20-30 item appetizer menu and found them to range from average to delicious. I think it's definitely worth exploring.
