First off what is Langostino? Its a crustacean that's very similar to a lobster in which only the tail meat is used. Honestly most people wouldn't be able to tell the difference. Anyways Rubio's has brought back their tacos and invited me to try some. The staff of the Rubio's I went to was amazing. Cleaning everything to a shine and asking how everyone's food was. I already knew that Rubio's has a solid fish taco so I was curious about the Langostino. Well its a good taco but I think the thing that puts it over the edge is their new fire sauce (tip for chiliheads its not fire) but its great on these and their fish tacos. Yeah I would go back and their (possibly housemade?) flour tortillas are a nice touch.
