Lisa Elmqvist seafood restaurant. Many of the vendors offer good take-away options if you feel like taking your lunch out to a nearby park for a picnic. The saluhall is open from 9:30am to 6pm Monday through Friday and 9:30am to 4pm on Saturdays, closed on Sundays. The closest subway station is Östermalmstorg (red line), just 4 stations from the Rival Hotel.
located at Hötorget (under the SF multiplex). Hötorgshallen isn't as fancy as Östermalms saluhall... but it is larger and you have the added bonuses of there being a liquor store (Systembolaget) inside as well as an outdoor fruit market just in front of the entrance. Be prepared... the vendors at the fruit market are very loud and vocal in selling their wares. They shout "half price only for you my friend" at each passerby. Good places for lunch inside! Open from 10am to 6pm Monday through Friday, 10am to 3pm on Saturdays and closed on Sundays. On Sundays the outdoor fruit market turns into a flea market. The closest subway is Hötorget (green line).
