We enjoyed our meal at Yianni's. The good things: nice decor - greek isle theme (blue and white) without being tacky - big windows, generally a nice place to spend time. This was an anniversary dinner for us, so it was special. However, while we like good food, we're not particularly into jacket and tie places, so this was a nice compromise there - no need to get all fancied up, but still, most people made an effort - no jeans and flip flops. The food was very nice. Honestly, it wasn't the best Greek food I've tasted, but it was good. We had the fried cheese (served flambe table side) and three dips as appetizers - the spicy feta dip and the creamy garlic dip were extremely tasty and the warm pita was delicious - very good pita. We were pretty full already after just that. But, of course we also had our main courses. Mine was a nice, but not amazing salmon dish. I do not recall what my husband had, but he felt the same - nice, but not really great. For dessert we shared one of the desserts, which was very good.
The thing that slightly took away from the experience was the service. Our waiter was only somewhat attentive and spoke very loudly. I got the feeling he wanted us to think he was amazing, moreso than the food and restaurant, but he tried to make that happen by "impressing us" with his grandeur rather than providing great service. He wasn't awful, mind you, but definitely a point commented on during the evening between the two of us on more than one occasion. Also, the policy seemed to be that our waiter would absolutely not top up our water glasses. Only some junior member of the waitstaff seemed to be doing this. We'd ask our waiter for more water after sitting with drained glasses for quite a while and still wait 10 or 15 minutes longer for water. That is something of a pet peeve of mine. It wasn't all that busy while we were there, either, lest one imagine that the staff were simply overwhelmed. Only about 1/3 of the tables were used at 7:30pm on a Saturday evening.
All in all, I'd go back and have no reservations about recommending the place. It's best for slow, lingering dining. More for adults than kids (although there were a couple of children there).
