We went in here during a Travelsphere tour of Costa Rica. It was great to find Subway where we knew what to expect. We were not disappointed. There was a long, slow queue, but I guess this is because the place is so popular. The staff spoke excellent English and made us welcome. They also pointed out the special offers we were eligible for (something like a free drink because we had 3 cookies I believe). The price was not cheap, but was reasonable. They happily let me pay by credit card (other places had first needed to see our passport as proof of ID). The toilets were a bit understated for the number of customers, only one male and one female could use them at a time. But on the day they were like an oasis in a dessert.
