Barcelona, Spain

Las Ramblas tourist traps serve €25 paella made from frozen seafood while the genuinely excellent Catalan restaurants require deep local knowledge to find and access. A study by Barcelona's tourism board found that 80% of visitors eat within two blocks of Las Ramblas, where average meal prices are 40% higher than comparable local spots yet quality scores plummet to 2.8/5. Even its best fine-dining experiences average €80 per person—40% cheaper than top Lisbon restaurants—but remain hidden from the average traveler, perpetuating the hype.
