I found Peppar Peppar via Tripadvisor. I was travelling alone in Uppsala and decided to go there, without reservation (in my experience it's unneccessary to make a reservation when you're traveling alone), on a Monday evening. The staff was not particularly friendly but they got me a nice table. Menu looks good, but not special. Very nice and still warm bread as a littel bit before the first course. Water (still) standard on the table. Good winelist, with large choice of wine by the glass. In short: the food has a very good quality, the service (friendlyness) could be better.
