I have written about this particular restaurant once before, but I wanted to add an update. I found this video of Chattanooga's Taco Rico which shows pupusa preparation and has some good shots of the food served there. The narrator is the son of the owner, and he is much cuter in person.
I also thought I would add more info on the type of foods served there.
Plaintain chips with red, green, and chimichurri sauces. Chimichurri is a sauce made with spices and olive oil. According to Wikipedia, it originated in Argentina but is used as far north as Central America.
This is an empanada. This one is filled with meat but you can also get dessert fillings. I tried one filled with sweetened yucca although I didn't particularly like that one.
The Plate of Day, a beef stew with rice and beans. It's served with tortillas on the side and is a good value at only $6. I would definetely recommend this restaurant if you want to go out to eat but are short on cash.
The unfortunately non-alcoholic mango drink comes in this decorative large glass. I tried a new juice type drink, the "maranon." A different taste that the waitress described as less sour than the maracuya (passion fruit) I had on my last visit. The waitress also informed me that this particular fruit is good for digestion.
