Whether you enjoy your Salt & Pepper experience will depend on your approach to Mexican food. If you prefer dishes like Tacos, Hot-iron chicken fajitas, or Enchiladas, S & P will deliver (it's hard to miss on these sorts of dishes), albeit at an inflated price.
It's worth the cost if you favor more traditional fare, such as their (cheap) Azteca soup, a fresh and hearty tomato-chipotle base married with chicken and avocado. Combine it with their in-house chips and salsa/guacamole and you may not need an entree. Their Mole is also splendid, the staple sauce starting out chocolatey sweet and slowly filling the mouth with a comfortable warmth. As is typical in these smaller Mexican restaurants, the amount of meat on the plate is low but the flavors are solid and mostly worth the price.
