By DENNIS WYATT 209 Living HALF MOON BAY — Talk about a quandary: You like mountain hiking and your date or significant other likes strolling along the beach. And to make the day or weekend special you’d like to have a nice place to dine as well as do some window shopping while keeping things low key and without emptying your bank account. (Or you can do that and stay at the Ritz-Carlton starting at $636 a night.) Half Moon Bay delivers on all points. It’s not Monterey.
