Sonic is the only drive-in restaurant in Waukesha. You just pull up in your car and the service comes to you. It serves breakfast, lunch and dinner. Breakfast choices are burritos, sandwiches, French toast and fruit. Lunch and dinner menus include such items as burgers, hot dogs, popcorn chicken, wraps or fish and chicken sandwiches. It has lots of yummy drinks, snacks and dessert items too. Great food and it's a fun place to visit. Happy hour is every day from 2pm to 4pm, when you can get half-price drinks and slushes.
