Heading to Lisbon and Porto for a pre-holiday trip with my girlfriend, 2 nights Lisbon, 1 in Porto. Looking for a few special venues, ideally local Portuguese cuisine, leaning towards the upscale. But overall someplace memorable, anywhere from modest to luxurious. Research here and elsewhere has provided a few ideas: In Lisbon, Olivier (noting mixed reviews) and Lisboa A Noite. Also curious about Eleven, though the recent reviews scare me. In Porto, leaning towards Foz Velha. Basically, if you had one night, what's the one place you wouldn't miss for the ideal experience in each location? Any and all suggestions/feedback welcome and appreciated. Many thanks!
