An example of an positive review: It's great that the national aviary is right here in Pittsburgh. Well actually, it's just the name and it's really not recognized as America's aviary. But on to the bird zoo. It's an awesome place with countless birds, including bald eagles, penguins, falcons, parrots, greys, and so much more. They aren't in cages, they fly and wander in natural surroundings. The best part of the aviary is meeting the penguins. Named mainly after famous hockey stars, Sid is the star of the penguins. The National Aviary is a jewel here in the burgh, I advise pittsburghers and visitors alike to flock to the aviary and help them stay afloat or this will be one of those bygone memories.

An example of an negative review: The food was good but the service at the front of the restaurant was terrible. I walked in with my friend and at least three people saw me and didn't greet us or get us seated. The girls just kept talking to each other and walking away from us. After 5-10 minutes of being ignored, a man asked if we've been helped noticing that I looked annoyed and I said no so he finally seated us. Mind you we were the only ones waiting to be seated and they weren't busy. After that the dining experience was fine and he waiter was nice,but I wouldn't go back. I can't stand when the service sucks! Especially when the girls were too busy talking and being rude. Do your job!

An example of an positive review: New owners but the same great food. My previous complaint about the potatoes no longer applies. The potatoes are now cooked properly, not under done like they used to be.

An example of an negative review: We've been to a lot of car dealerships in the last few weeks, and this was hands-down, the worst experience of the bunch. We were first ignored, then made to sit and wait for pricing for more than 20 minutes, for no apparent reason. We will definitely not be going back.
