A good rule of thumb when measuring how good the salsa is at your favorite Mexican restaurant is the chip-to-meal ratio. If you end up downing a whole basket of chips before your cheese enchiladas even get to the table, chances are that the salsa is superb. So be forewarned: If you decide to dine at Lopez's, you might never even bother with the main course. This large bright yellow restaurant just outside Beltway 8 recently moved down the street to larger digs, no doubt because their delicious salsa was bringing in fans in droves. The dark red, chunky dip is made fresh right at the restaurant, and while waitstaff suggest a "secret recipe," we detect plump tomatoes and spicy peppers just by taking a sniff. Like any good salsa, it's strong stuff -- by the end of a meal your eyes water and your sinuses clear. But if you're still craving more by the time the check comes, you can take a large plastic tub of it with you for just $2. Pick up a bag of chips on the way home, and you won't even need to bother making dinner.
