I've been going to King Eider's for a long time now and I always enjoy my meal. In addition, I like the vibe, and best yet, I can go there with the teens and they find something to eat every time that they really enjoy or I can go for more of a date night if I like, and it works for that too. Not too many restaurants can be that flexible. If you go to the little oyster bar upstairs, you are at a bar, in terms of the seating, but they also have a small table in there for two as well. Sitting at a bar isn't my favorite way of eating with a friend. Hard to eat and look at the person and talk. But the oysters are fantastic! So I suggest getting a regular table, even that room is actually kind of cute. It's a good place to go if you want to watch the hockey game with a friend and have a drink and a dozen or so. But not for conversation.
Downstairs is the pub area. It's a pub with a bar, bar seating, tall tables for two with bar stool ind of chairs, and also some bench seat tables. It's nice. Intimate. A little darker than upstairs. Service here is probably not quite as good as upstairs, which is where the waiters seem to be a bit more on the ball (maybe they are nearer to the kitchen upstairs...).
Upstairs in the regular dining area, not the oyster bar area, it feels like a family restaurant. They can easily accommodate a large group by shifting things around.
The soft pretzels are a huge hit with my kids. They get those every time. My kids also have deemed the hamburgers and fries excellent. I get a fish meal there most of the time and I find they cook all fish dishes well. Good flavor. Maybe a bit bland for my tastes, but then, most straight up American restaurants fall into that category for me.
Seating outside isn't all that exciting. View of the handicap parking space, a small road, and the sides of some uninteresting businesses.But if you really want to be outside, the tables are fine and have an umbrella over for shade.
All in all, I've never had a bad meal here, I've frequently had very, very good meals here (my all time favorite is the lobster stew which is the best I've had in Maine so far), and the service, while not entirely reliable, has for the most part been pretty good. One time they were super slow so they comped us a glass of wine and a beer. I thought that was the right thing to do.
