True Food Kitchen is a nice find in the Domain that has a variety of interesting gluten free, vegan, and vegetarian options available. While a little on the pricey side the food was good, the servers were attentive, and the patio seating is dog friendly (they even have dog bowls for water for your fuzzy friends).
We tried a variety of atypical gluten free options including Ramen and Lasagna with a desert of Squash Pie. There were lots of options for interesting things to eat for those that are gluten free, not the usually one or two items you see at some restaurants. All food choices were generally good. Our gluten free folks remarked especially on the Lasagna. The Ramen and the pie were both reasonable. We also tried the hot chocolate, which was wonderfully yummy and not too sweet, and a Matcha Horchata which didn't taste much like Matcha, but was a totally reasonable green colored Horchata. Our server was great and paid close attention to our folks with dietary restrictions, which was much appreciated. Parking was easy as there was a parking lot immediately adjacent and a free parking garage less than a block away with lots of available parking pretty much all the time. The patio seating was pleasant and they fully supported us bringing our dog (even gave her a water bowl that was appreciated after a long day of hiking around Austin). Overall there weren't any criticisms other than the cost, but it was pretty typical of things in the Domain which tend toward a little higher cost offerings.
