100% authentic legit Mexican food. Portions are huge and very affordable, my burrito which I couldn't finish was only $5.50. You can also get fresh fruit juices, 32oz for only $2.50. The staff will even let you try a sample of the juices of you can't make up your mind. Your meal also includes a salsa bar with tortilla chips. These are big thumbs up in my book.
As a bonus you can even shop in the supermarket and the prices are very reasonable.
The only drawback is that it's in a somewhat gritty neighborhood and not everyone may feel comfortable going here.
