Had not been to MC for 10 years as worried about security. This trip, never felt safer anywhere, lots of security everywhere. Tierra de Vinos is in a nice neighbourhood (Colonia Roma). All the wine available is laid out in alcoves by country of origin, so you can browse the bottles. Service attentive and friendly. Our party of 6 shared some tapas then a few main courses, food was better than I expected. Would definitely return. Nice ambience.
