The first time I ate at a José Andrés restaurant was in Las Vegas circa 2017. Jaleo was — and still is — located on the third level of the Cosmopolitan (one of the more glam Vegas hotels, situated mid-Strip, just south of the Bellagio). Its mission is to celebrate the flavors of Spain — the chef’s homeland — and to showcase the rich regional diversity of Spanish cuisine.
I remember that the food at Jaleo was really, really good, but what truly won me over was how careful the staff was with food allergies and intolerances. Gluten-free options weren’t listed on the menu, but the staff had detailed information about what would be safe for me to eat, and they were savvy about cross-contamination.
