Past Delilah's and Finnigan's Wake, down 3rd Street in Northern Liberties, lies a nondescript building on a desolate block, identifiable only by a blue hand-painted sign. This is Ortlieb's Jazzhaus, a tucked-away piece of perfection. Home to Ortlieb's Brewery a century ago, Ortlieb's Jazzhaus has been home to nightly live jazz since 1987, featuring famed musicians such as Mickey Roker and Bootsie Barnes. Ortlieb's also features a Thursday jam session -- all musicians present are invited to sit in with the band after its first set.

Ortlieb's cozy dining room is long and narrow, with the stage as its clear focal point at the center of the room. Spotlights illuminate framed photos and album covers of jazz musicians that line the walls from tableside to ceiling. A wall-mounted buffalo head and strings of unlit holiday lights are Ortlieb's concessions to decor. Ortlieb's theme is simple: no pretenses or distractions, only great food and jazz.

The clientele is diverse. Dressed-up 20-somethings pick at rib-eye steak and popcorn shrimp as gray-haired couples in jeans and polo shirts enjoy pork chops and jambalaya. The cuisine is Southern/Cajun-inspired, with many menu items named after musicians. We enjoyed spicy yam fries and mouthwatering steamed mussels, followed by Sid "Piano Man" Simmons' blackened catfish and salmon from the weekend specialty menu. The fairly comprehensive wine and beer list features everything necessary and nothing extraneous. All entrees ($12.50-$17), come with a soup or salad; appetizers are generous ($4-$10). Service is relaxed and friendly.

It's difficult to decide whether music or food reign supreme at Ortlieb's. Drummer Mickey Roker's quartet drew oohs during solos, gentle laughter at familiar tunes and raucous applause. During the set, conversation can be difficult; also expect to be shushed if you interrupt a sultry saxophone solo. However, the spicy and delectable cuisine ensures appetites are sated. Don't miss the yam fries, coated in Cajun spices and served with two dips. The first, a jalapeno-honey sauce, is sweet with a spicy finish. The second sauce, chilled sour cream, perfectly balances the fries' heat.

Ortlieb's oozes the soul and vibe of jazz. Portions are generous and irresistible. Patrons linger long after the completion of their meals. Dim lighting, sexy jazz solos and intimate seating make Ortlieb's a perfect first date destination. Its affordable menu, delcious fare and overall atmosphere, however, make the visit to Northern Liberties a necessity for all.
