It's easy to screw up a first date. You could: a) come on too strong or not strong enough, b) bring a vegetarian to a steak house or c) spend the evening detailing your sexual history. If you have a propensity for answer c, we can't help you. But choosing the perfect first-date venue could solve your other problems. Backstreet Cafe will send your date the right message. It's classy, but it's not Mark's -- that would signify that you're trying too hard. At Backstreet, there are no tablecloths, but there's a sommelier. The menu offers not only sandwiches but also fancier steak and fish dishes. And just in case your date has forsworn flesh, there's a killer veggie plate. The restaurant is a converted two-story house with intimate dining areas in several rooms, and its easy combination of romance and casualness will set the perfect tone for your evening. If you manage to steer clear of ex-talk, you're virtually guaranteed a smooch or two.
