We all like a sure thing. Like a rerun of Seinfeld, a steak dinner at Durant's, or the latest White Stripes CD. And in Tempe, when it comes to "neighborhood Mexican," Restaurant Mexico is a no-lose proposition. Tucked into a brown block of businesses just east of Mill Avenue, Restaurant Mexico has got it going on: simple yet tasty Mexican cuisine, such as enchiladas in tomatillo sauce, burros, chimichangas, tostadas, and some of the best sopes we've ever had, covered with chorizo and salad. Even Restaurant Mexico's refried beans are better than average. And the prices will put a smile on the face of a starving student. You can eat like a king for about $10. Perfect for that first date with the cutie from Chemistry 101, or that Sir Studly who sits across from you in Sociology.
