Pozole in Denver?
I haven't had the posole at Tarasco's but I really like the place and find their food to be pretty solid generally speaking. Most of the posole I've eaten/ordered has been in menudo and there are plenty of places along Federal & East Colfax that have menudo on the weekends. :)
If that fails, it's a simple dish to make at home and high-quality ingredients for the dish are pretty readily accessible here in Denver.
