I took the wife and kids up to Wells this weekend (spending overnight on Sunday for the Monday holiday).
Staying overnight in Wells, Maine this time of year is a GREAT value. It's quite easy to get hotel rooms for less than half the price they'd be during tourist season. We found a place called The Elmwood resort on Post Road (Rt. 1) across from a Dunkin Donuts and since it had showed that it had a vacancy, we parked there and got ourselves a bargain: For $95+tax, we got a two-bedroom suite with a kitchen, a total of three queen sized beds, and free wireless internet--perfect for a family.
Unfortunately, my wife was feeling under the weather with what turned out to be a stomach virus, so it was just the kids and me going out Sunday evening.
After thinking a bit, and not wanting to go to, say, the Grey Gull without my wife, the kids and I decided to go to a place we hadn't been to in a while: Mainiax. This is a family friendly place with a lounge and seems targeted to tourists with its moose and lobster theme. When we got there Sunday evening (7pm), the place was mostly empty.
I ordered the fried fan-tail shrimp, which I enjoyed. Although it was served with cocktail sauce, it was easy to get the waitress to bring out tartar sauce.
My oldest daughter had the "Shrimp Lover's Special," which included stuffed shrimp, fried native shrimp, and fried coconut shrimp, and she enjoyed that immensely (almost too much for her to eat). She shared some of my tartar sauce...!
My youngest daughter ordered the small prime rib, and when it arrived, it looks like they opted to send out the larger cut instead. It was done the way she likes it, as well, although it was a bit much for her to eat completely (she really had expected the smaller cut).
On the way back to the motel, we stopped at a little Chinese take-out (sorry... forget the name) located in the Hannaford's shopping strip to get my wife a small egg drop soup ($2.25). It turned out to be the perfect thing for her upset stomach, and she really enjoyed it.
It was a nice overnight trip, and it wasn't too expensive for a family junket. I'd recommend trying Maine's seacoast "out of season" for great deals and great food.
