I happen to like De Cero but can see its faults. After many visits, I have found items I truly love and can keep the price of dinner down, somewhat. Here's what to try: the duck nachos--if you do not like duck, you can sub chicken. Order the guac (not the salsas, as they come with the taco platter). Have the regular margs w/o the premium booze--they are $8-$9 and not bad (or go across street to Perez where margs are much cheaper and better as the food can be, too). Agree that you must have tacos. I love the battered catfish, tomatillo pork and chipotle chicken. The tamales are also surprisingly good. If you have a sweet tooth, try the chocolate brownie. You will not be disappointed.
If you can handle $12-14 margaritas as the servers try to push you into their "premium" versions, and don't mind paying $3-4 dollars for a tiny taco, you'll have a great time, if service isn't something you expect at a premium priced place. De Cero was one of my bigger restaurant disappointments within the past year. It was a second visit, and was a mirror reflection of the first.
Others will disagree, but I LOVE De Cero. Here's a few tips to ensure you are happy:
1. Only order tacos. Do not order any of the other entrees. They have about 20 different kinds of tacos on the menu and you can do a "flight" of them as your meal.
2. They excel at their pork tacos. The other meats are pretty good, but I always find myself loving the pork ones.
3. Don't expect amazing service.
You will have a good time. And I promise you someone will order an entree instead of tacos and will say "eh".
