Standout, real-deal Mexican and Central American eatery Las Americas on the restaurant-flush Nolensville Pike strip unassumingly adjoins a small grocery – you actually pay your bill in the grocery – and features one of the city's most interesting and well-prepared menus of its kind. Las Americas' signature dish, worth the trip alone, is the pupusa: a fried cornmeal pastry filled with your choice of pork, pork rinds or cheese, with refried beans and spicy cabbage slaw on the side. A childhood favorite of El Salvador native Juan Cruz, who owns the restaurant and grocery, this delightful dish is inexpensive and filling enough to sate a light eater or for a couple to share as an appetizer. The small, double-shelled and eminently tasty tacos feature all types of beef (chopped, pulled, tripe, tongue and cheek), although we're particularly smitten with the chorizo, Mexican sausage that is chopped and fried crisp. The shrimp enchiladas and the raw oyster cocktails (a dozen swimming in a stein filled with house-made cocktail sauce) are also highly recommended. For hearty appetites, the burritos are among the city's biggest and best. A reason to dine here on weekends is the Sunday-only offering of caldo de mariscos, which is a seafood soup chock full of the star attraction. Desserts include flan and pastel de tres leches (three milk cake). Bottled beer available. Serving lunch and dinner daily.
