We've had both dinner and lunch buffet there. We thought the food was decent (the chicken tikka masala from the menu was pretty good) 2 yrs ago, but last year when we ate there, it wasn't very good and I asked the waiter if the management had changed--he said no. We might give them one last chance when we're in the area (since we have the entertainment card).
Akbar is still on my list of Indian restaurants, but kinda by default -- they've been around for a very long time. That said, I still think they were top-notch when they first opened on Coit Rd.back in the late 80's -- long before moving to their present spot in Plan Zero.
Their food is just... kinda... typical northern Indian fare. Now back in the 80's, ANY Indian fare was considered about as exotic as food could get here in DFW. But now, there's so many choices. One thing is for certain, Akbar was there at the beginning of the Indian wave.
