While formality has its place, sometimes casual is best, explaining the proliferation of the tuxedo t-shirt, and why you always opted for college "casuals" with far less girls in dresses and way more video games and your roommate asking why you're crying again, despite wearing your hilarious tuxedo t-shirt. Now casually re-opened: Aria.
Closed for several months to overhaul its look/concept, the previous "Trattoria" has just quietly re-opened as a simpler, less Italian-y "Pizzeria & Bar", swapping white tablecloths for banquette seats and mahogany-stained columns for sports-casting flatscreens, all to better serve their Reagan Building-heavy clientele, who demanded faster and cheaper lunches, so they could quickly get back to wondering how you acquired 46 dependents. The menu's been completely reworked, with starters like portobello mushrooms/peppadew/goat cheese on crostini, and around-$10 entrees (previously ~$30) including a baked pasta section, grinders like an onions/peppers/provolone Italian Sausage joint, plus pizzas like a mozzarella/ricotta/Gorgonzola/romano, and a White pie with just mozz and ricotta, because contrary to popular belief, not everyone loves Romano. Awkward business meetings're lubricated by 12 taps (including three from Charlottesville's Starr Hill Brewery), as well as a fresh cocktail list (many available in rare-for-DC pitchers) with everything from the apple liqueur-in-a-Stella "Belgian Apple", to the Maker's/simple syrup/soda/fresh mint "Aria Julep", to the tequila/Cointreau/simple syrup "Tequila Mockingbird" -- drinking one will cause everyone to look at you, Radley.
They've also installed a sizeable bar in their heated seating area, half of which is outdoors and half of which is covered, perfect for rainy days when Dark n' Stormys're dropped to $5, and your level of formality's subsequently dropped to your morning jacket scrunchie.
