Cute atmosphere, vegetarian + low carb options?

Hi! Visiting soon. I'm a vegetarian and my partner has to eat a pretty low carb diet due to a medical condition. Which usually means we end up getting some sort of Asian food, but open to anything that has options. We're staying downtown and going to the Kendrick Lamar concert at the NRG stadium, so places around there would be great, but down to drive farther too. Thanks!
