Great food good price.
We love Portumex! It's a family owned, family friendly place with great food at reasonable prices. We especially love the ceviche, but the carnitas is also delicious. They give you a lot of food! Go hungry.
You order at the cash register. There is almost always a line, but you should be able to find a table. It's busy for a reason. It's kind of a hole in the wall, but all the locals know about it, and it's very popular. The service is friendly and fast.
