An introductory summary of Taco Bell seems silly -- it's America's most ubiquitous fast 'Mexican' food joint. And if you haven't already eaten there, you're doing so willfully and/or you're Encino Man. However, if it's been a good while since you've last partaken from the 'Ken-Taco-Hut-Silvers' tetrad, know that their menu changes with the seasons. General rule: the closer to closing time you eat there, the better it tastes.
Lobby closes at midnight.
