In honor of the new century and the ever-improving ballpark neighborhood, Mexico City Lounge has done a thorough house-cleaning -- right down to remodeled bathrooms and a tiny expansion that put two tables in the former kitchen -- and moved the kitchen to the back of the old Larimer Square storefront. The change in kitchen locations apparently necessitated an oil change, too, because everything coming out of that kitchen tastes much brighter and fresher -- even the notoriously greasy and great steak tacos. But the real health food here is an order of bean tostados: three crisp, oil-free corn tortillas topped by just-mashed refried beans, along with shredded cheese, lettuce and tomatoes. Squirt on some of Mexico City's special salsa, and olé!
