Morning: Only came once for a group event at the buffet, and it was nice. I had a cheerful server who promptly answered my request for "a very strong coffee" and brought me a huge espresso.
Normal dining hours: Fine. Though it's been a while since I've come here for that. There's one server who used to work here who was an absolute delight. I hope that more people work here. I find Eat'n Park's food to be average and kind of overpriced for their quality, but the familiarity of the food is welcoming.
Late night: Ugh. The service is horrible, and the food is more subpar. I use to come with friends who work at a restaurant with me, so we are very forgiving, and we get really frustrated at the inattentiveness of the service here, seemingly by really apathetic annoyed teens. They're really not trying at all. Aside from the convenience of the location, going elsewhere would probably be a better bet. The food tastes kind of stale about half the time we come here at night, like dry chicken tenders, soggy fries, etc. The other half of the time it's acceptable, but again seems really overpriced to me for the quality and even the portion.
This is the only Eat'n Park I've really tried, so I can't really speak for other locations, but I would definitely not come to this one late at night given the choice.
Late night - 1 star, normal hours - 3 stars. So averaged at 2?
