re: Hill Country Eats

Roughhouse brewing is on a ranch and has good sandwiches and tacos
Devils Backbone Tavern, while not food, is near the lake and is an old school bar and has big name bands play there.
In Wimbereley, The Leaning Pear has great outdoor seating on the creek and the food is local sourced/seasonal. Chill's on the Creek is a good casual place with great outdoor seating on the creek. Community Pizza is good wood fired pizza and a great beer selection.
10 minutes north of Wimbereley is the Shady Llama which is an outdoor beer garden where I can spent hours looking at the view and watching the sunset while sipping a good selection of craft beer. They have a food truck that has good tacos and burgers.
In New Braunfels, Guadalupe Brewing has great pizza too.

Comfort may be too far from the lake but High's Cafe is really good food and nice outdoor seating. There is a winery and a distillery just behind High's that is good for a stop.

Boerne has some good places too with Cibolo Creek Brewing that has a farm-to-table menu being one of my favorite.
