Fronterra Grill- Chicago's and possibly the U.S.'s best upscale Mexican restaurant. PBS chef Rick Bayless creates classic but inventive, true Mexican dishes. The margaritas have been picked by some as the best in the country. But be warned they can be addictive and will run up your bill in a hurry not to mention ruining all other margaritas. Fairly informal, Topolobampo, which is attached is more formal. No reservation are accepted and the wait can be long. Newly opened Xoco next door is Bayless' take on Mexican street food. 661-1434, 445 N. Clark, L D Tues-Sat, $$$ Website
Salpicon- Upscale Mexican food in a formal setting with a extensive wine and tequila list. It would be my favorite upscale Mexican restaurant if not for Fronterra Grill. 988-7811, 1252 N. Wells, D, $$$ Website
Adobo Grill-
Decent Mexican American food in a fun environment. We eat there after going to the zoo or before going to Second City. Good marguerites and guacamole, 266-7999, 1610 N. Wells, L D, $$$ Website
Blue Agave- Above average Mexican American food in a party atmosphere. The chorizo burritos, our favorite, are especially spicy and are a treat not found in most Mexican-American restaurants. 335-8900, 1050 N. State, L D, $$
Mixteco- Very good, true Mexican food. Best moles I have found north of Mexico. Informal, BYOB 773-599-5538, 1601 W. Montrose, D, $$
