Craft beer bars, here in the USA anyway, usually offer a "sampler
platter" where you get a few ounces each of several different
selections. Even if the sampler is not listed on the menu, I've
found most places will accomodate your request. Also, if you ask
for a taste of a specific beer, typically they are happy to oblige.
