It has been about 4 years since I jaunted to College Park from DC but CP used to be a culinary wasteland.
I'd recommend you look at Silver Spring, not far away. Two places to check out are Jackie's and Ray's The Classics. Ray's The Classics (and his other 4 or 5 places in the greater DC area) are extremely well-regarded and, relative to other steakhouse places they compete with, comsidered great values for our area. The decor is usually pretty plain intentionally but is nice.
Jackie's is regarded as somewhat hip. Ray's is known for their good food and value.
