Interesting how different two peoples' experiences can be in the same restaurant on the same night. We clearly had different servers and I'm sorry your party wasn't as lucky as we were.
Dino hasn't been perfect in the times I've been (IMHO, the wines, cheese, meats & crostini are outstanding, while the pastas & fish less consistent) but I remain a big fan and my experience last night was my best yet.
I think its important to keep in mind that different restaurants have different aims. Dino, in particular, lists its goal on its website. Spawned by the proprietors love of small family style wine bars & restaurants in Italy with very good reasonably priced wine and noting the absence of such establishments, Dino does not purport to challenge the Citronelle, Maestro, Obelisk elite, but simply states "Our desire is for you to enjoy our authentic foods and wines in a comfortable, casual setting." I for one am very grateful and think that Dino insightfully spotted a real glaring hole in the DC dining scene. Maybe I'm just on a tigheter budget than most, but I think Dino is the perfect spot for someone who loves food and splurges for a fancy meal on occassion, but wants to have good product at a more affordable price on a regular basis.
