Things that are challenging: not hitting the drink during presidential debates, parking in Georgetown, and finding a Mexican restaurant that has both cheap food and decent drinks. We can only solve one of these. Taqueria Nacional will fill you up on food for a cool $10 in the form of tacos, quesadillas, and tostadas without skimping on the drinks. Boldly colored margaritas flow, so too do spiked agua frescas and drafts of Mexican beer. You might remember the taco shop from its Capitol Hill days, but now Taqueria Nacional fills an old post office on T Street NW in a space that’s as sexy as Salma Hayek. Hit them for “prime time happy hour” during the week when drinks are deeply discounted from 7pm-close.
