Been to Stonehouse about a dozen times, one of my favorite lunch/dinner spots in Westlake. The staff across the board (hostesses, waitresses, bartenders) are very friendly and welcoming, not to mention provide excellent service.
The place is extremely clean and welcoming, a good sign when you walk in to a neighborhood restaurant. The food is very good at a reasonable price. I recommend the burger or the New York strip steak salad (two of my favorites) and throw in a cup of their tomato bisque, you will not be disappointed.
I would check it out for lunch or a weekday dinner, it is always packed during dinnertime on the weekends.
