I've been to Jaleo in DC and definitely don't remember it being as good as my meal at Jaleo in Vegas recently. Food was solid, great lively atmosphere and people watching into Cosmpolitan :)
Service - good and fast!
Sangria - The white sangria is extremely unique (Cava, Gin and other deliciousness) I highly recommend it
Some favorites from the meal:
Croquetas - Best croquetas I've ever had
Carne Asada - Perfectly cooked and delicious
Other notes:
Patatas Bravas - More like potato chips than potatoes, a little non traditional
The one thing that was just "ok" was actually the paella! I like my rice al dente but I thought it was a little too al dente? The lobster meat over it made up for it though. So decadent!
