I recently visited Jaleo (Crystal City), which is a short and beautiful walk from the metro, for restaurant week.
First off, I have to say that while the Crystal City Jaleo location is beautiful, the Downtown location has better food.
The classic red sangria. I would have loved to try the sparkling white Sangria with strawberries and mint, but it only comes in pitchers and I was dining alone.
Bread was served with high quality olive oil with rosemary and garlic – very good. I ordered spinach with pinenuts, raisins, and apples and pan con tomate (rustic bread topped with crushed fresh tomatoes and manchego cheese) – both were very good. The fried, bacon wrapped dates are my favorite thing ever (though they are better at the downtown location). On the menu it says “como hace todo el mundo” (that you will want to eat every day) and they are not lying! They are the perfect combo of salty and sweet. The calamari was decent but not outstanding.
Desert was a very good flan with Espuma.
