Barros Luco opened a few months ago on 52nd and 2nd. The eatery is named after its featured item--a Chilean sandwich known as a "Barros Luco" named in turn after a turn-of-the-century president of Chile who was known for holding court while snacking on these bad boys. The Barros Luco comes in either steak or chicken, on what looks something like a hamburger bun but with a smoother and lightly glazed surface (a slightly denser texture and a definitively doughier flavor), and is served with any variety of toppings, including melted swiss-style cheese, tomatoes, avocado, green beans, and banana peppers. I had the "Charcatero Completo," which is essentially the aircraft carrier of toppings. I thoroughly enjoyed. The green beans give it a benign but noticeably novel flavor. The eatery itself is highly comfortable, with several tables (including booths) on the second-floor that look out floor-to-ceiling onto 52nd. (Incidentally, the fountain Coke is excellent--nice syrup-to-CO2-water ratio.) Only criticism, and it's slight: the sandwich is filling, but not huge. If starved, you might put away two (perhaps giving rise to an opportunity to house both the steak and the chicken), but at $7-$9 the double-barros shotgun approach would come at a price.
