There is likely not a more elemental Mexican-American dish than nachos. This borderlands staple — invented somewhere in between Mexico and the United States — is frequently looked down on as the lowbrow foodstuff of bowling alleys and movie theater snack bars. But most everyone secretly loves nachos, a dish that marries flavor and texture in beautiful and delicious ways. If you're a secret (or not-so-secret) aficionado of nachos, consider paying a visit to Juan's Authentic Mexican Food, an old-fashioned and unassuming Mexican restaurant on Thomas Road, where the nachos are made in their full and abundant glory. Get the Supreme Nachos, which are loaded with your choice of beef or chicken (the ground beef seems to work the best), plus generous scatterings of tomatoes, green onions, beans, and of course, small lakes of melty, buttery cheese. It's no secret that it's delightful.
