A place like Daphne's isn't going to be a Yelp superstar, but that does not mean it is bad. Personally, I find their food pretty good for what it is. It's a chain....not a hole in the wall, mom & pop Greek restaurant. Once you have an understanding of that going in, it isn't bad at all! I know I can go here, grab a quick meal to go, and be happy.
I always get the gyro pita...which tastes just like most other gyros I've had, yum, the pita has always been soft/fresh. Along with my gyro I usually get a side of dolmas (stuffed grape leaves). Not the best dolmas I've had, but again, for a chain they taste freshly made and always satisfy.
I gave it 4 stars but only because there was no 3.5 :)
