The 4 of us friends are BIG beer drinkers, and are looking for some fun places to hang out during our week trip in October. We prefer bars that serve domestic beer, as my husband is not really a fan of the local beer. Of course, atmosphere is important, but moreso we're trying to find places where we can drinks lots of beer at a reasonable price. Yes, we've been to Aruba (but only once before) so we know prices are gonna be high no matter where we go. But we're trying to get some tips of good bars, local bars, even "holes-in-the-wall" where we can get the best beer prices. We are VERY casual people, we will not be looking for anything fancy, just very laid-back and very casual places we can slug beers all night! Any bar in particular have good happy hours?
Thanks for the help!
