We've been to Zen before but we returned a little while back for a small family gathering. Zen is a Japanese restaurant in Hawthorn, and the night was a great success. Sometimes we've had the set menu, but on this occasion we had a few entrees and starters to share and followed this with individual mains. My beef was great, and I think everyone else was very satisfied, too. Our group was in the rear area, which after a while we had to ourselves (it was mid-week). The service was spot-on and the bill was pretty reasonable.
