Not quite one of the most depressing airports in the world but close to it. Depending on what time of day you arrive you'll generally be faced with exceptionally long slow moving queues at immigration. Luggage usually appears on the conveyors quite quickly and from this point on clearing the airport is reasonably easy - and you want to clear the airport! The shops available are reasonably far and few between food establishments are slowly getting better and are no longer the mum and pop owned places they were a few years back but are quite overpriced and poor value for money (even for an airport) probably due to the lack of competition. Transport from the airport is ok with buses and taxis easy to locate. The local state governor is the director of the only taxi company that has a taxi stand at GRU which probably explains why they have the monopoly there. Airport buses are available near terminal 1 and are easy to find and pay for even if you don't speak the lingo.
