It's almost a mile to the Harbor or any ""beach"" from Hennessey?s, so ""beachfront"" is misleading. If you want to go there to have a pleasant dining experience, don't go when the bar is going off and your odds multiply. I've gone there and to the Fish Bucket (part of Hennessey's) next door lots of times and it?s always been great food/service, but most of the time it hasn't been party time either. Otherwise, Hennessey's is just that, a tavern. People go to drink a lot, of course be with friends and meet new ones, and I love to people watch, as some people drink way too much and it borderlines between amusing and scary. And some of the women dress along the same lines. The people tend to be friendly (servers even, but I meant customers)--that's the bonus I guess from being a ""beachfront property"" (ha ha) vs. an edgy city club. Go with no expectations, and you might have a good time. If you?re on a night out and you feel old at Hennessey?s (which shouldn?t happen b/c there?s a broad age range), there?s always the Renaissance nearby, which is more upscale and mature. Otherwise, not much nightlife here in DP.
