Started eating there when it was called El Nopilitos and was doing business on North Main, across the street from Val's...equally awesome but no longer there. This was in the late 50's and early 60's. Back then my cousins from Vancouver, BC visited had dinner with us and at "El Nops" and he food had them crying from the unfamiliar spiciness. We Colorado kids gobbled it up and laughed at the lightweights...and we loved the spicy stuff.
A few years later El Nopilito moved up to its current location on East Bridge. The bigger dining room was a good move and kept the locals hooked up with good north New Mexico offerings. I don't remember exactly when El Nopilito became La Placita but in high school after every football or basketball game in the late 60's "La Plaz" was where everyone headed. The burritos, tacos and enchiladas rolled out rapidly and the kids eat it up.
Continued eating there as long as I live in Brighton, but in 1980 moved out of town. What a loss. Last September a group of us had spent a week dove hunting south of Ft. Morgan. As we drove home we got hungry at mid-day and I asked my fellow hunters if they wanted one of the best Mexican meals they had ever had. All said OK, skeptically, and we slid down off of I76 to La Placita. After the chip and salsa, and after the sumptuous feast, all sincerely said, "That was one of the best Mexican meals ever...ever...ever.
