My wife and I are always looking for great food bargains and great Mexican food. We were pleasantly surprised at Ochoas.
They have two locations in Hillsboro, and we have eaten at both of them. Each is similar. We favor the house special which features 3 tacos, 3 enchiladas, a chile releno, carne asada, steamed veggies, rice, beans, grilled onions, and fresh, homemade tortillas. Enough food (easily) for two at 6 bucks!
Tip: don't expect a shiny floor or spotless conditions. These folks save their attention for the food. Also, if you want napkins, just take a roll of paper towels off of any table. And don't forget the salsa and mole’ bar - their sauces are the best!
