There are tons of places off of Chandler Blvd and in/around the Chandler Fashion Center (mall). For Mexican, there is also Abuelo's and El Zocalo (nice outdoor patio) right off the 101 and Chandler Blvd. There is also Valle Luna off of Ray Rd a bit to the East.
For traditional/American there is Famous Daves (decent BBQ), Firebirds Grill, and BJ's. The Rock Bottom also has great food/beer, but is a bit to the West (off the I-10). For good Chinese (at least more authetic then most), C-Fu is excellent for lunch (Dim Sum) and dinner. For Sushi, I'd probably hit Sushi Eye, or Sekai in Mesa if not too far away.
Great, now I'm hungry!
