I often find myself needing to grab a quick bite to eat in the evenings, without wanting to wait a long time, either for the food to be prepared, or to stand in a long line to order (sorry, Torchy's). I'm talking about the kind of place you can pretty consistently walk in and place your order and get your food quickly. I'm interested in either eat-in or to-go places. I've specified Central/South because that's where I live, but I'm interested in places downtown, South Austin, East Austin, and central Austin up about as far as 45th St., as those are places that I can get to relatively quickly. I'd prefer if the places were open in the evenings (sorry, Habanero), because that's the meal I most often want to eat out. What are your standbys? Any great food fast?
