I can recommend: Las Ramblas Golf Club Restaurant
Last night we went to Las Ramblas Golf Club Restaurant for the first time in a long time. It was superb! The setting is beautiful, service was great, both waiters very entertaining, excellent singer called Rikki and all the food was amazing. For the main we both had the fillet steak, although we were served two each, with foie and an Apple and blueberry sauce. Cooked perfectly and just amazing. Starters and deserts were also excellent. The prices are very reasonable, 21 Euros for fillet steak with a Sichuan sauce. Really cannot praise this place too highly.
