My Portuguese friend took me here for dinner.
WOW. Really awesome and really authentic. I didn't understand word of what was going on (all the ordering was being done in Potuguese, but they do speak English)
We shared a mixed seafood plate which was absolutely to die for! Giant shrimps, lots of lobster and mussels. The food was incredible. Bread, olives and cheese were served before the food arrived.
Service was fantastic, they were over constantly refilling water, topping up the wine and making sure we were enjoying our meal.
The other clientele seemed to be all Portuguese. I'm assuming they come for a reason.
It wasn't cheap, but I didn't pay, and I really enjoyed it :)
