Wanted to send along a thanks to the fodorites who helped make this a delightful trip.
We stayed 2 nights at the Old Bank House (suggested by matt54) and enjoyed it enormously. As it has @ 8 guest rooms, it's not as twee as many of the smaller B 'n Bs. The rooms are unusually furnished with some fascinating stuff, the breakfasts excellent, and a lovely location.
We ate at Excelsior (unusually delicious) and at Grill-on-King (almost as good). garyt22- G-on-K is only 2 years old, located pretty close to the Shaw Theater. Service and presentation excellent, food very good. (Excelsior spoiled us). Had many customers, many looked like regulars.
Saw two evening theater performances. A "Touch of Venus" at the George, was fun, "The Women" at the Shaw was a little dated. Both shows were very professional and had very elaborate and clever sets and costumes. (though acoustics at the Shaw were not the greatest)
We visited 3 wineries - did one tour - bought some wine, had some oysters too!
Before NOTL we spent a night at the American Falls (Comfort Inn's the Pointe) and visited Cave of the Winds.
When we left NOTL we stopped at the Butterfly Conservation Center (I think it's called) - well worth a visit - and then visited the Canadian Falls before heading home.
Only disappointment with NOTL - shopping not to my taste - too conservative- (DH didn't mind!). Otherwise a perfect trip.
