I went to Salt & Pepper's (I think that's the name) on Monday and I'd have to say it's the best Mexican food I've ever had. Prices weren't bad, $10-$15 meals, but the quality of the food and the atmosphere were just amazing. If you like real mexican, try this place. Beats the crap out of Taco Bell and Tacotime anyday.
Mind you the Cantina on 8th Ave. isn't that bad. You can't go wrong showing up on a tuesday during 'Gringo Hour'. $10 will get you a couple tacos and a bottle of sangria. Fed and tipsy, for $10, that's hard to beat.
