It's the Tenderloin, for god's sake, not some food court in Danville. You expect a little atmosphere.
Once the food arrives, you won't notice anything you'd previously tagged sketchy, especially if you order the extra-succulent chicken tikka masala, saag dal (lentils and spinach), and garlic naan.
And it's all cheap as hell, which makes the whole Tenderloin divey thing seem downright charming. Pakwan, 501 O'Farrell (at Jones), 776-0160.
