This place was frighteningly crowded when we went. Urbana-Champaign has a lot of restaurants, but judging by the teeming masses at Dos Reales, you'd think it was the only place to eat in the entire universe. They have a "wait until your number is called"-system, which worked okay, but that's only because one of us heard the faint shout of our number being called.
I have nothing against the service or the food. The service was incredibly fast, given how many people were in that vast Mexican food labyrinth. Our server was nice, too, which I wouldn't have expected. The chips and salsa were tasty, as was my food and margarita (the margarita was strong, which is oh-so-important). We got to stay as long as we wanted without getting the stink eye. Not too shabby.
