I have been here for the regular dining menu in the dining room, and for the happy hour menu which is served only in the bar area. Both are great.
You can check out the Happy Hour hours and menu on their website under menus. The bar is very small....probably holds about 20 max. So since it is so beautiful outside by the river most choose to sit there. Word of warning: IF it looks like it could rain you might opt for inside, as rain can come up suddenly and then its like musical chairs with 40 people going around but when the music stops only half have chairs! You cant just all run into the dining area either, it rains often enough and that would be too disruptive to the diners in there.
If you are going to end up eating several plates at $4 or $5 each, maybe just going to the dining room would be worth it. They bring a little loaf of bread and its a nicer room to be in.
If you just want a smaller bite and a drink the bar is fine too, but you have to read the hours of happy hour on the website! Varies by day.
There are gardens on the west side (side toward Portland). They sometimes have weddings there. Sometimes I get some good flower pictures there too! Nice to walk around there before or after eating.
It has a good feel and you feel like your way of of town, go check it out!
