I can't say enough good things about Marinelli's. The food is amazing ("homemade" pasta made fresh every day), service is top notch and friendly, prices are reasonable. I've dined there several times, and have never been disappointed with their pasta dishes. I've heard mixed reviews about the steaks, ... but quite honestly if you are going to an Italian restaurant for steak ... well, you get what you deserve. I highly recommend the roasted peppers as an appetizer, along with the walnut and olive breads. And the italian chopped salad is amazing, and quite reasonably priced.
Don't forget to grab a few chocolate mints as you're walking out the door. I have friends who eat at Marinelli's just for the mints - they are that good.
