I've been here a few times. I've had the gyro meat twice, tried a pork chop, and was given a small sample of the chicken. The first time I was there, the meat was a little dry. The other times I've tried the food, it was delicious. The pork chop was kind of amazing. Service was very friendly. The meat is a bit salty and I could do with more flavor in the rice. All in all, though, I like the Sultan Grill and will be back.
Also, they serve two types of tzatziki sauce. I recommend you ask for the thin version.
