Mercado is a grill and bar with 75 tequilas on hand and 20 beers on tap. Marcel Link, the owner, was inspired to revamp the menu, making it more authentic, after a recent trip to several cities and small villages in Mexico. He also enlisted help from Julieta Ballesteros, the chef and owner of Creama and China Latina in New York, making the fare more upscale. The menu has little devil icons to indicate just how spicy dishes are. There's a prix fixe on Wednesday and Thursday, and Tuesday night offers $2 and $3 tacos.
