Ready for an X-rated meal? When ordering your chili, keep in mind that 'X' is mild, 'XX' is spicy and 'XXX' is melt-your-face-off hot at this Austin institution. There's more than just chili on the menu; there's also Frito pie, which is chili over Fritos. Still not feeling it? There's also burgers, enchiladas and, of course, more chili.
