Here are some other places in Lubbock that I really enjoy that I haven't seen listed. These aren't chains and may or may not be in a nice building so fair warning.
Choo Chai - Khao soi with rice. I would suggest getting the mild. He makes his dishes really spicy so anything above mild is very spicy. And don't judge the book by its cover.
Thai Thai - I don't remember the names of the soups but I remember the numbers of 36 and 37. One soup has more vegetables and the other has chicken, potatoes and onion. Fyi, don't ask for substitutions. There's a reason we call him the Thai nazi.
Another dish there that is very good is the genghis khan beef.
Thai Pepper - I really like their pad thai with a medium spice. I think its the best in Lubbock. I also really like their panang curry.
Saigon - this is a Korean place that I really like. If you like spicy then try the spicy pork it's great. They have a barbecue pork that is more sweet and it good as well.
Taqueria Autlan - I have only eaten at this Mexican place once and I really enjoyed it. I have been meaning on going back to try different dishes.
If you are in need of a breakfast burrito then you need to go to either Picantes which are big breakfast burritos or Burrito Tower. At burrito tower, I love their migas rancheras burrito.
Finally I have to suggest going to Hawaiian BBQ. I would recommend the beef plate. I would suggest getting the regular plate because it is a lot of food and also get the pot stickers.
Ill add more places as I think of them.
