Tango Sur on Southport is a great little hotspot for juicy argentian-style meats. Next door, you'll find El Mercado, where you can buy the meats, the chimichurri sauce and all the fixings that you'll need to make that special spanish-inspired meal. Ask for a fresh, hot empanada - and definitely take home a container of their chimichurri sauce (kind of like a pesto) and add it to your own chicken/beef dishes in your kitchen.

PROS: interesting selection of foods
CONS: do not take credit cards
