New addition to Surprise and a welcome addition. I've been a couple of times in the past week and have happy with the food.
This is the same Rivas that is located in Phoenix and Tempe. The menu is extensive, prices reasonable, portions large and the food tastes pretty darn good.
The place won't win any awards for decorations, but the food makes up for it. They serve breakfast, lunch and dinner with an assortment of options for each meal.
This place also has a drive through, which according to the take-home menu is open 24 hours.
