I usually go to Zepra once a month. The starters and small dishes are superb, so don't settle for the main course. They also have neat cocktails worth tasting.
The last time I went there was with my 5 year old daughter which really enjoyed it. I too was impressed with the top kids-oriented service: she got her own kids menu and some drawing activity, her meal came out first and pretty fast too, she really liked the meal (which is way better than the crap they give kids in some places) and even got a small ice cream in the end. Well done.
Also: once or twice a year Zepra changes its menu for a couple of days to the chefs old and now-closed restaurant - Chimichanga, that served excellent New-Mexican food, modern style. If you get the chance you should definitely go.
