This is a cute place that my husband took me to one evening when he was unexpectedly craving a coney dog. My husband doesn't particularly like hot dogs of any format so I was pleasantly surprised.
Although the coney dogs were good, they had yellow squirty cheese on them which was a little overpowering. We were expecting a coney dog with meat sauce, stadium mustard and onions. The hot dogs, although tasty, were miniscule and engulfed by the buns. There was ample food for the money and the root beer was delicious!
Sadly the night we visited the place was a ghost town... it was a weekend evening and there were 3 cars total in the parking lot.
One pitfall is that we drove our convertible - it was a beautiful evening weather-wise. This caused problems with the drive-in tray that attaches to the car window. The trays at Retro Dog are designed for car windows which run straight up and down - unlike any car today that is aerodynamic and has slanted windows. Our server nearly dumped our dinner in our laps when trying to attach the ill-designed tray to our window. This situation was followed by a perplexed and confused look from the car-hop who offered no solution other than to hand the tray to my husband and I so that we could "figure it out" ourselves. Unlike Swenson's (which obviously plans for car-side service year-round) Retro Dog doesn't offer (or our teenage waitress didn't know about) a special tray designed to fit INSIDE the vehicle.
IF we visit again we'll be eating inside. Much ado about nothing.
