Dali is a busy, quirky, restaurant with very good food and great service. We've eaten several times and have always enjoyed it.
They have excellent Gluten Free and Dairy Free menus (and vegetarian dishes are clearly marked on the main menu), which makes it quite pleasant for those of us with a dining partner (my wife, in my case) who has food intolerances or allergies. Our server was extremely helpful in ensuring everything we ordered was allergy "safe."
We always get the tapas, which range (and another review said) from exceptional to just "good, but nothing special." There are some nice little touches as well. For example, they have a sherry flight that comes with a detailed description of each offering.
And I love that they provide a little sign that maps-out the meats and cheeses on the Plato Mixto, so you know the TYPES of each sample. Also strongly recommend the Gambas al Ajillo (a classic, really) and the Pinchitos Morunos de Pollo (chicken kabobs) which are super great.
Definitely recommended; Always fun. Get there early (like, before 6:30 on a Wednesday) and you can walk-in and grab a table. Otherwise, reservations are strongly recommended. You CAN sit at the bar and order food if there's space and you don't want to wait.
