For those who are familiar with these two towns, I'm planning a trip for my wife and me and another couple to visit several parts of Portugal in early June. I'm pretty well finished with the itinerary but thought I'd ask this esteemed group what restaurants you might recommend in Lisbon and Porto and, if possible, why you would recommend them.
Suggestions of what I would classify as budget places (under 40€ for a couple), standard tier places (40€ to 100€ for a couple) and splurge places (100€ and up for a couple) all are welcome. I recognize my price tiers may be out of whack with prices on the ground in these cities, but that's how I usually think of these things. We like most any kinds of food and especially seafood, which we are looking forward to enjoying. We're also planning to take a food tour the evening we arrive in Lisbon and expect to pick up some recommendations from the guide.
I'm familiar with the usual online sources and am using them, and I also have slick Rick's guidebook for Portugal. But what I'm looking for here are recommendations based on personal experience.
