I adore Harley's. My absolute favorite pasta dish in the valley is their gnocchi with pesto sauce. I could eat this stuff every day of the week. It's decadent, full of flavor, and cooked to absolute perfection. While I thoroughly enjoy their standard tomato sauce and vodka sauce, they don't compare to the pesto sauce. I would PAY for the recipe for that pesto sauce. It really is stellar.
The bread they serve is also wonderful and addictive.
The few times I've dined inside rather than picking up my order, the service did leave a bit to be desired. It either seemed like they were understaffed or simply inattentive. Never anything overly annoying though. And the delicious food more than compensated for any minor deficiences in service!
