Los Trios restaurant
RESTAURANT SALVADOREAN & MEXICAN FOODS
BAR AND GRILL

This is my favorite Mexican place in Frederick. I'm rather surprised by the one-star reviews here. If you're expecting crunchy tacos with hamburger meat, iceberg lettuce, and a puddle of refried beans with cheese on top, then yeah, you're going to be disappointed--this is not that kind of Mexican restaurant.
It's true that some of the wait staff don't speak the best English. Deal with it--it won't kill you. I've never failed to communicate my order with a bit of patience and good humor. It's also true that the music is sometimes a bit loud, especially when people are gathered around the bar--so don't come here if you're looking for an intimate fine-dining experience.
Do come here if you're looking for good Mexican, Tex-Mex, and Salvadoran food, carefully prepared from fresh ingredients. The tortilla chips are the best in Frederick--fresh and hot and flavorful, with an emphasis on quality over quantity. The tamales and the pupusas are both great. I usually get the chicken tacos, but almost everything I've tried has been good.

Friendly people, really really good food, good prices. My wife loves the soups. The fresh guacamole is great. Our favorite Latin restaurant.

Great food. I got lunch to go. Good spices and taste but ask for extra spicy if you want something spicy hot.
