Neon beer signs glow brightly in the cool darkness. The taco and tostada are made of old-fashioned ground beef with a minimum of seasonings and a maximum of chopped iceberg. The tamale and rice and beans are served swimming in chili gravy. Larry's seems indistinguishable from dozens of other vintage Tex-Mex joints -- until you dig into the cheese enchiladas. Then, while you're working away on the rolled tortillas, a miracle takes place on the plate. Viscous yellow cheese sauce oozes into dark brown chili gravy in yellow and brown swirls, creating a delicious masterpiece of half melted cheese and half tangy enchilada sauce. This goop that's left on your plate after you finish the enchiladas may be the crowning glory of old-time Tex-Mex. Pass the tortillas, please.
