Only go here if you can keep a secret: part of Sleeping Dog Cafe's charm is the fact that it's never too crowded, even though it's in the heart of downtown, tucked in the lower level of the Plaza Mercado. Its unique yet accessible menu, including steak frites and chipotle-mango pork ribs, and drink specials -- like martinis -- make this cozy restaurant the perfect place to have a quiet lunch or dinner. Definitely a hidden gem.
