For city-dwellers, it's a pretty torturous tease finding such a great happy hour all the way out in Hunt Valley, but if you can somehow arrange for a cab or DD to get you there and back, this is a no-brainer. It's kind of hard to believe that the Oregon Grille has a happy hour at all, given its special-occasion feel (jackets required in the dining room) and baller prices-indeed, here it's referred to as "Classic Cocktail Hour," which is 4-7 p.m. weekdays, incidentally. But the deals are, like, kind of crazy: On Thursdays it's $5 martinis-and not some crappy rail hooch, any gin or vodka you want (!). And get this: free oysters. Fridays they have a free sushi bar and Wednesdays, free steamed shrimp-like, what does that even . . . how? Note that this is in the bar only, which can get a bit tight. But the excellent drinks and impeccable service are likely to impress even more than the free food.
