As a Brit in Madrid needing replacement glasses I went to two of the big chains nearby and then…read morealso to Optica Ordovas in my street. A really excellent experience and easy to select them over the others. Charming staff, enormously helpful and patient, and a thorough examination. Prices already reasonable (for Madrid, where glasses are generally expensive) but they gave a discount for being local even after I'd agreed to buy, and then threw in an extra case when I couldn't make up my mind between two. Like being in a different world.
