Recently, I read an article about a Cuban trailer floating around the city. I've always been a germophobe and thus avoided street food, so it wasn't until I heard multiple accounts of the wonderful food that I made the 10 mile journey to investigate this further.
First, I had to call the chef on his cell phone to see where he was that day. He rotates between three dealerships: Oxmoor Ford, Mazda, and Toyota.
Based on reading the forums at louisvillehotbytes.com, I ordered the Cuban sandwich and, as a side, the rice with chorizo. My second choice would've been the sweet potato fries though.
The sandwich contained ham, marinated shredded pork, tomatoes, onions, and pickles, with a creamy yogurt sauce and optional cayenne pepper. (The pepper adds just a hint of spiciness without being overwhelming, so don't be scared to ask for it.) I decided not to get the cheese. This was extremely flavorful and a bit wet, which made for messy eating, although the bread was not soggy. I happily devoured this in the front seat of my car since it was raining outside and I abandoned my idea of eating it in the nearby mall. This is the best Cuban sandwich I have ever had, far surpassing Havana Rumba's, because the latter's pork is simply boiled and has almost no flavor.
The chorizo rice was a little salty and greasy, but also packed with flavor and a generous amount of meat.
The menu also features breakfast omelets, Mexican torta sandwiches, Cuban ribs, quesadillas, and an interesting selection of several Cuban desserts. It appears to be a one-man show. This chef has worked at a number of restaurants and told me that business has been slow this winter because people don't know he's certified by the health inspection board.
Bottom line: if I lived closer, I'd come more often to El Rumbon. Call 502-210-9087 if you are looking for a fantastic, cheap lunch option (and if you're not a vegetarian). They're only open on weekdays from 9 am- 3 pm. :)
