I love super duper and it's the place that I have to go-to anytime I'm in town. The garlic fries and milkshake are great but obviously the star of the show is the burger. This location is great because it's far enough from Moscone that the crowd doesn't really make it out to here.
By far one of my favorite burger restaurants. Perfectly treads the line between fast food and fancy restaurant style burger. Really good fries too, nice thickness of fry, and nice & crispy. Their complementary (read: free w/ meal) homemade pickles are the best. Sometimes I get something small here just to have the pickles. The staff at the market st. location are always friendly. I work in the office in the same building a few floors up from the restaurant, so some of the employees are starting to recognize me and my co-workers. Alos, try their breakfast sandwiches! If you like the McDonald's breakfast sandwiches, you'll love these even more.
