No wi-fi, no cappuccino, no dress code and no service past 2:30 in the afternoon. That's what makes the 20th Street Cafe our favorite breakfast bar. But the prices -- which top out under the ten-dollar mark -- also make it the best place in Denver for breakfast on the cheap. The venerable cafe isn't fancy, and it doesn't have the most convenient parking in the world, but it does have a good chicken-fried steak, huge omelets, good diner-style coffee with fast refills and a menu that mixes up the best of classic Americana with an interesting take on the Colorado immigrant experience, including fried rice and noodle bowls that call to mind the Japanese war brides who once settled in the area.
