Boca Chica
I just came back from the DR, and I can say that BC is just the place for guys,,,,during the day the beach is what you can read here in other posts in more detail and at night time, you see the same old thing up and down on Duarte.
There are few places to eat where service was good as well as the food.
Try Italy Italy,,, great pizza, and the place on Duarte with a fountain and lots of picnic and high tables,,, great German style food with a Dominican twist. Also D'Nancy behind the Hamaca, great Seafood Risotto(Asopao de mariscos)
I would recomend you check out Bella Vista on the beach, those guys there will treat you nice, if you like mixed drinks, they make them with fresh fruits, and for some reason, vendors were not on top of us all the time. They also offer a good menu and a very beach-bum-relax area plus free Internet.
I have been at EL Candil, and nothing but good things to say about them, from security to service.
Try posting again so you can hook-up with somebody,,,, if you are not into the night scene or being chased by babes, it can get boring if you don't have someone to share few drinks after the sunset and talk about everything and nothing at all. I was never in BC before all the clean up was done according to the posts here, but to me is a really working girl enviroment at night time.
We were there few days and after dinner, we walked up and down on Duarte, had couple of drinks and just did a bit of people watching,,,,,as we are not into the night scene either,, and I can't imagine a "solo" guy like you enjoying that.
PM for more details.
