  • "Rachel and I stopped by Westgate Petroleum yesterday. Great experience. Professional and courteous staff, nice interior, good coffee, great gas prices and an excellent wine selection, possibly the nicest Lake-County-only I've seen. From a wine industry viewpoint, I'm particularly happy there's a good fuel stop on that stretch for tourists. It gives exactly the impression guests want when touring the county!"
