OK, Sweet Pea and I love us some Coup, and it's not just because we've been coming here for years- since I lived across the street and could see the restaurant from my window- or because we got engaged here (which was incredible.)  It's because the food never disappoints.  You can go to restaurants and have varying experiences from the best meal of your life to terrible, but Coup is not the place for that.  It's consistent.  And consistent can be good, or bad.
As consistently good as the food is, the service is likewise consistently slow (albeit friendly).  We went here for Valentine's day which we've been several times and I highly recommend.  It's romantic without being showy.  They have a special Valentine's Day set menu of 4 courses which is always interesting and good.  And, if you go on the day before Valentine's Day, they still have the menu, but it's cheaper.  Damn those greeting card "holidays".  The menu is also consistent.  The outstanding things are the brie brulee which is an absolute must-try as an appetizer, and the lamb shank.  Everything else is solidly good without being great.  The desserts are exceptional.  I like the BYOB aspect of the restaurant, although, they do charge you a lot for "corking fees", which amount to just charging you for nothing since they have a corkscrew sitting on the table and you are in charge of opening your own bottle.
Coup, I love you.  You get 5 stars if you vary your menu a little, please, please, please get more vegetarian (if any vegetarian) options, and improve your service.
