Solero (Rec 60, Borne) You probably didn't come to Barcelona searching for California style Asian fusion. However, Solero is definitely worth a lunch or two. Everything is organic and they may have the best salad in town. If you're lucky the salad of the day will be lambs lettuce and have slices of grilled egg plant. It's close enough to be convenient but far enough from any sites to avoid being mobbed by tourists. Service is slooow but friendly. We've been going here for lunch at least once a week for a few months and the menu hasn't repeated yet (8.50 euros including dessert and wine). Our only disappointment was a Pad Thai which turned out to be Mie Goreng and even that was pretty good except that Cheyenne didn't care for the (sunny side up) egg on top. Expect about 20 euros per person if you order a la carte. Calle Rec may not appear on the tourist maps but it starts and Princessa, cuts across Passaige del Born and ends up near the Estacio de Fracia.
Senyor Parellada (L'Argenteria 37, Borne) Hardly a secret but worth a stop especially if you're looking for traditional catalan dishes. We originally tried it because it is open on fiesta days and Sundays when most other places are closed. The atmosphere is upscale but the prices are very reasonable. Try the seafood stew (Caldera al Mariner), the duck with figs (Anec amb Figues), and the lluc (aka merluza or hake). I didn't like the flan (de nata) because it was too eggy and rich for me but I've never had "flan de nata" before and maybe I just don't like it in general. Expect about 20 euros per person. The restaurant is attached to the "Hotel Banys Orientals" (3 stars) which -- although I haven't actually seen the rooms -- judging by the lobby and the restaurant would be a good place to stay if your budget allows 85 euros per night.
