This latest from the dynamic duo, chef Fabio Trabocchi and partner/wife, Maria (see Fiola and Fiola Mare), shimmers with waterfront light and a welcoming sparkle. The two-level restaurant is huge, but it doesn’t seem so: Intimate spaces are carved out within, each with its own style, but sharing an overall attention to beauty and comfort and Spanish accents that Mallorca native Maria Trabocchi undoubtedly had a hand in. High ceilings, jade-green banquettes, a green-shuttered windowfront room overlooking the waterfront, a large, circular bar punctuated with sea-blue cushioned barstools, and handpainted ceramic tiles underfoot are just some of the charming touches. Del Mar focuses on the tastes of coastal Spain, so expect excellent grilled fish, paellas, marinated mussels, grilled wild squid, and such. Selections of tapas, Spanish cheeses, charcuterie and raw fish are available at every meal. A short list of “principal plates” might include a chorizo burger and a Mallorcan-style lobster (served with stewed baby potatoes). The croquetas (creamy fritters filled with jamon Iberico, i.e., Spanish ham, black truffles, and green garlic aioli) are a must. As comfortable as Del Mar is, it still feels special, so it’s worth dressing up a little to come here, even during the day. In fact, it's required: The restaurant permits no flip-flops, athletic wear, or torn clothing and requests that “gentlemen refrain from wearing shorts, sandals, sleeveless shirts, or hats.”
