Aranda's is pretty spectacular. I'm not sure if it's a blessing or a curse that they're located in DeForest, because on the one hand the restaurant is a bit out of the way to attract people coming from Madison or Sun Prairie, but on the other hand DeForest's small town nature easily lets Aranda's stand out as a great restaurant.
The salsa to start you out is superb - a perfect balance of cilantro and spice. I am also a huge fan of the Mojitos here! I love the drink's appearance in the glass mug with sugared rim, but what really makes them excellent is that the mint flavor is stronger than the lime, making it less acidic and, in my opinion, more refreshing.
I ordered the Cristoval's Special and my bf had the carnitas and we were both extremely happy with our meals.
I say that Aranda's is worth going out of your way.
