The thing is about Greek food, is more often then not for a good dish you're forking out (no pun intended) aprox $14 per meal. Maybe then $8 per appy and $6 for dessert. The one thing I really like about Yianni's and can not stress this enough is that the food is clean. Not too much oil, not over seasoned (could have used more lemon on the dolmathes but other than that) it was reliably good Greek. Maybe more so the way Mom used to make it if you get my drift. The long-time employees are friendly and seem to genuinely want to help you when it comes to either making a reservation or just ordering something.
I'd give Yianni's a 8/10 for good, clean, solid service, food, & ambiance. It's reliable and not too dressy for a night out- but still a pleasant place to dine and enjoy a hearty meal.
