Best downtown breakfast/lunch

Need help from downtown experts. What are your favorite places for breakfast and lunch?

El Sombrero for lunch.
I also like the Brew Pub at Main Street Station (777) and the little eatery for Chicago Brewing Company at 4 Queens.

Agree with t_b and here a few other favorites:
Le Thai for their Pad Kee Mao.
Tacos El Gordo for their adobada tacos.
Luna Rossa for their eggplant parmesean.
Aloha Specialties for their dirt cheap teriyaki chicken bowl.
Thai BBQ for their Pad Kee Mao and Tom Kha.
