I tell you what, there is certainly no shortage of places to eat in this town, in fact some days it seems like the ONLY thing to do

Anyway, as far as my favorites go...
Pizza-Big Freds (120th and Pacific area)
Mexican-El Azteca (I-80 and Hwy 50 area)
Chinese-House of Hunan (132nd and Center)
Thai-Bangkok Cuisine (19th and Farnam)
Vietnamese-Vietnamese Asian Restaurant (Yes that's the actual name,72nd between Dodge and Pacific)
Japanese/Sushi-Sakura Bana (74th and Dodge)
Cajun/Creole-Mother's (14th and Saddlecreek)
Steakhouse-Anthony's (72nd and F)
Sandwich Shop-Jimmy John's (Yes, I know its a chain, but I swear they put crack in their bread! Various locations)
Italian-Sorry, but as an Italian who grew up in Brooklyn, none of the local places are up to my, admittedly ridiculous, high standards. If I have to do Italian, I go with Lo Sole Mio or Carraba's.
"Bar" Food-Either Millard Roadhouse (132nd and Millard Avenue), or The Rusty Nail (144th and Pacific).
Vegetarian-About the only place in town that is considered a "vegetarian" restaurant is McFoster's, but I was NOT impressed. You're better off going to one of the Asian restaurants.
Coffee-Crane Coffee (A local chain with various locations)
