For me to give a 4-stars, it suggests I have to come back here again so pretty impressed by the inventory of maps they have: not only international, but even gas/mining and other geological literature out there too.
Guy was super helpful, even offered me a free tourist map of DT since that's all I initially wanted, but I'm here to do business so better I get a more detailed one.
Amex accepted.
Also, some globes for sale too.
Located ground level of a big office building.
