This is one of my favorite spots in Las Vegas. I've been here for both brunch and lunch/dinner, and always on the patio. The service is always fast and friendly, and the food is really good (noting complicated, but they always get it right). I do believe they have gluten free and paleo options. The crowd is pretty hip, and the size varies. The last time we were here, we were one of maybe three other parties. The time before that, there was a wait to be seated. I don't think reservations are really necessary, but you can definitely enjoy walking around or sitting at the bar while you wait for a table.
