Castro Indian Restaurant & Bar has measurable pull: 3,949 all-time Blackbird check-ins, with Saturdays and Sundays leading the traffic. Google backs up the crowd with a 4.7 rating across 531 reviews.
The review signal is flavor-forward and comfort-heavy: Chicken 65, lentil soup, goat curry, and vegetarian coconut curry all get called out for big seasoning; Chicken Tikka Masala linguine lands creamy and comforting. One reviewer said they dropped in at 10:30pm while out in the Castro for cheese garlic naan, chicken tikka masala, and garlic fries.
