Believe it or not the best Korean food in the Denver area is found in a little eatery inside the H-Mart grocery store in Aurora. None of the fancier places can measure to it, they are simply too westernized. The best way to find these little authentic eateries is to ask immigrants, which is how we found this place.
The service is fantastic, the super nice waitress knows us now and knows what we love so no need for menus. The prices are more than affordable. My favorite dish is the Sun Tofu soup. I would eat it morning, noon and night.
You will never see me in a posh Korean place in the Denver area. H-Mart all the way for us.
