Heading over to O Trevo, I was expecting a tourist trap. Many of the restaurants featured on travel shows have become inundated with tourists and have had a decline in quality. Thankfully, O Trevo was a quick stop and we'll worth the detour. It is busy, but service is super fast. There are tables, but people are also eating right on the service counter in front of the cashiers and cooks. Just grab a spot and enjoy.
My meal, a sandwich with an large beer, was about €7 and it was one of the most delicious things I had in Portugal. We had phenomenal food on that trip, including eating at a couple of Michelin star restaurants, but somehow this no frills sandwich was my favorite. And, it's specifically the Bifana at O Trevo, we had a couple of others elsewhere and they did not compare.
This sandwich was full of tender, juicy, flavorful pork stuffed into a lightly crispy, soft roll. I had cheese added, which was great, but totally not necessary.
One quick thing to note, BRING CASH, this was one of the only places I visited in Portugal that was cash only. There is an ATM outside, though it was broken while I was there. There's also a bank not far away in the same square.
O Trevo is worth your time, there's a reason locals continue to go there despite all of the tourists. It may be full of tourists, but it's definitely not a trap.
