Waiters whirl through Grimpa Brazilian Steakhouse's streamlined interior, dancing with swords that skewer more than 15 kinds of meat. Diners can sample steaks and an 18-item salad bar and hot buffet in the art-strewn dining room or on the outdoor patio, where swaying palms and ghost cowboys bring to mind traditional gaucho camps. An onsite wine cellar accommodates international vintages of red, white, and bubbly, and an à la carte menu allows chefs to pair tender cuts of beef and fish with gourmet sauces and sides.
