Calle 3 is lined with the main park, at least eight small market/grocery stores(of various sizes) almost all operated by people of Chinese heritage, dozens of restaurants and bars, dozens of water taxi/ adventure operators, and perhaps ten clothing/souvenir stores. Oh yes, above most of all these businesses is a hostel.
Just outside of Bocas Town and just a 10-15 minute walk from our condo is Bocas Brewery. They are right on the beach and the main road out of town. They do small batches of beer, much heavier and higher in alcohol content than the local mass-market Balboa and Panama brands. I think our son's could be the brewmasters in such a place. Of course, Bocas Brewery's beer is also a premium price ($5 per pint vs. $1.50-$2.00 for a 12 oz. bottle). They also offer a half-pint of Chilean wine for $3.50. On Wednesday's they have half-priced wings which are very good. They also have a larger bar menu.
