The best restaurants serving Mediterranean food in College Southwark London

(Note: this restaurant is also known as 'siOn') We booked because the restaurant was within walking distance of Dulwich College - but not without trepidation as the website is aimed at diners forty or more years younger than some of us. We need not have worried, we were all made very welcome. siOn was taken into five-star territory by the quality of the food, which was excellent. We ordered a wide variety of 'smalls' and 'sides', eaten tapas-style, not a duff amongst them. Music a bit on the loud side, no hot drinks, short wine list, great cocktails. Friendly, attentive and responsive staff. No automatic service charge. An easy five stars.
