Having lived in this area of the Mile End for a little over a year, I can attest to the fact that Taza Flores is a gem that is frequented by mostly locals (especially by those who are attempting to be a bit frugal without sacrificing food quality). This spot also doesn't succumb to same aura of hipster-pretentiousness that plagues other restaurants/bars of the Mile End.
Last night, I went with a few people and shared four tapas, including Eggplant Pizza; Cod Fritters; Grilled Chorizo; and the Vegetable Platter. All of these options were fantastic, flavourful, and made with delicate care by the chef in the bar area. Having initially expressed some skepticism around the cod fritters, this particular tapas ironically blew me away. It was fried as the name implies, and served with a rich and creamy tartar sauce.
While the service was exceptionally good, I'd suggest in the future that they explain the options more in-depth without being prompted by the restaurant guests (ie. explain each aspect of the vegetable platter tapas).
Fun tip: Go after 11pm and order three tapas for ~$23.
