Raising Cane's is wonderful. They only do one thing, chicken fingers, and they do it well. Side dishes are cole slaw, fries, and Texas Toast, and you get all of them. Plus they have the regular beverages. Don't ask them what kind of sauces they have, cause that brands you as an outsider.

They have one type of sauce, Cane's Sauce, and it is really yummy.
Winchells is a typical tavern/pun. Drinking/smoking/slots one one side, which is closed off (so no smoke in the restaurant) and food service on the other. They used to have house made potato chips, which are always really good. Don't know if they still do. But as a rule of thumb, anywhere you go, house made chips are good.
Which brings me to the Oyster Bar at South Point. Inexpensive meal would be clam chowder (comes with French Bread). White or Red, your choice. Looks like not a lot, but man oh man, is it filling! And they have house made chips, which you can also get to go (don't put them in the fridge, they will get soggy).
If you want prepared food but don't want to cook, Whole Foods is on the fringe of Town Square. They have many kinds of foods that are already prepared, and a huge cheese bar.
For Stations Casinos Military Mondays, go to Green Valley Ranch (of I-215 at Green Valley, turn right, then immediately right again into The District. We often go at lunch, and as I said it becomes under $11. for two. You could also wander around The District, there is a Crazy Pita there, a Panera, an Elephant Bar, Lucille's and more.
I've heard many people rave about Bacci Burger. However, I went there once with a group of about 20. It had been prearranged, it wasn't a surprise. They lied to us about how they would do things, then took what I would consider a tremendous amount of time to bring our food. Then they lied a bit more. They obviously weren't able to accept such a group easily, and shouldn't have booked us, but I'll never go back because of the way I was treated.
I didn't provide you with links but if you put the names of the places in Uncle Google, you should find all of them. I only provided things East of I-15, on "our" side of town. Karen will tell you about Summerlin.
