Porto restaurant register: smart-casual + Burel wool acceptable; Lisbon restaurant register: smart-casual + sandals + lighter cuts. Cross-shopping: Burel Factory + Claus Porto + Pelcor cork-leather are Portugal-wide brands available in both cities; the Porto-specific Luís Buchinho + Felipe Oliveira Baptista contemporary Portuguese designers stock primarily in Porto.
