Also, a number of nice restaurants are scattered about that serve delicious, multi-coutrse meals and drinks at a fraction of the cost in the USA. Some places even include live entertainment to add to the ambiance.

You can walk down the street and shop for a variety of items including leather goods, pottery, jewelry, perfume, toys, wood carvings and knifes.
