Each year I plan ahead and make spreadsheets for each of the various day parties. This is the first year that I will have a separate sheet for food deals and freebees. It'll be almost as important.
The major things I've sighted this year include the Yelp half price festival of all things tasty. To make a long story short, read up here. There's also Addie Broyles' ridiculously helpful list on Austin360.com
As far as my current picks, I'm going to be hitting up Uchi, Sugar Mama's, House Wine, Taverna, and the full Irish breakfast at BD Riley's. If I had $75, I would go to the BBQ crash course hosted by the great folks at Dishola.
There's so much to be excited about. And that's just the restaurant deals!
