While the jungle decor and fish tanks on the first and second floors of this Adams Morgan bar can seem a bit like Disney World for big kids, the popular hangout has at least one feature everyone can get behind: the year-round roof deck. Enclosed with heat lamps and a tent during the colder months, the mosaic-decorated third-floor bar feels like spring break in Key West. It’s also one of DC’s last remaining sanctuaries for social smokers.
