I've done all the touristy stuff, all the out-of-the-way places, judged for quality and my own tastes. That said, my perfect food day (non-tailgate) in T-Town would be:
Rama Jama's for breakfast. Center-cut ham and hash browns with a biscuit. All the football atmosphere you can handle and then some. Then I'd probably have to hit the gym and burn it off because for lunch I'd want:
Swen on the strip. My favorite Chinese place in the free world. Fresh and delicious and the owner is so friendly. Best Mongolian Beef ever, just the right amount of crispy vs. tender. Then I'd have to take a nap, run a few miles to burn off lunch and head to:
Local Catch for dinner. Every seafood dish is great, the apps are might fine (pork belly!!!) and the bar is nice. But not so nice that I wouldn't leave and head around the corner to shut it down at:
5. Friendly staff, top-shelf booze and reasonable at that. Nice atmosphere, especially if it's warm enough to sit on the street.
