Like their counterpart Carlos O'Briens, Macayos knows what it is. They make simple American-style Mexican food with a big helpin' of cheese. Also like Carlos their quality has dipped some of late, but it's still a decent place to get a bite to eat.
If you're eating in their cheese crisp is a treat (but a little goes a long way) and their chips and hot sauce are really good.
I used to like getting their red corn tacquitos, but they're consistently under-cooked and doughy in an unpleasant way when I order them now.
Apart from that most things on the menu are decent if desperately unhealthy.
The best thing on the menu is probably the Chicken Poplano--a poblano chili stuffed with chicken, breaded, fried and buried under baja and enchilada sauce. An extra 200 flights up the treadmill if you order it though. It's not light eating.
Overall it's a decent place with good service that could be a lot better with a little more consistency. And please fix your red corn tacquitos. They used to be great.
