If you happen to be driving by the Riverside area and come upon Pollos El Regio, you're in for a real treat. They have a combo where you can get a whole chicken, rice, beans and tortillas for about $15. It's one of the best pollo asado anywhere in town. They also have a really good salsa.
The only downside is that it's only pick-up. They've only recently added some tables but they're only outside. However, you can totally make it a picnic if you buy a real Mexican soda there too.
