Priya on University at Addison has an excellent buffet, lunch and dinner. There’s a large variety of dishes that I’ve never seen elsewhere. They often have a tasty (but bony) goat curry. Chicken tikka masala is usually available. $11.99 for the buffet.
Down the street, I’ve had good meals at Indus, a Pakistani place. Most dishes are under $15.
Back on Solano, House of Curries at Curtis has some of my favorite combination lunches. They also have goat. Heated patio in front. Prices around $12.
