Anyone been to First Emperor on Polk Street in Richardson? The frontdesk clerk at my hotel recommended it. It is a classic hole-in-the-wall Chinese restaurant. No real ambiance or decor. I truly felt like I was in many of the places I've been to in Taiwan. I was the only "non-asian" in the place. My dish was very very good. Something called East Chicken. A mix of chicken, ginger, and I think a little onion, and lemon grass and some spicy pepper. It was quite tasty and very inexpensive.
My guess is the local Chinese community is well aware of the place. It looks like it's located in a mini-Chinatown based on the signs on the other establishments in the area.
Did a quick Google search and didn't find much. It's located near Texas Instruments corporate offices so I'm guessing it does a big lunch business.
