The quality of food at the recently spiffed-up Bolton Hill staple hasn't wavered at all since it opened almost 10 years ago. George Dailey, the owner of On the Hill and the erstwhile Centros Tapas Bar in Federal Hill, sources eggs from Springfield Farm in Sparks; the well-kept chickens there produce superior eggs, in taste and texture. So whether you get a plain ol' egg sandwich with cheese ($3.75) or one with spinach and cheese ($4.50) or one with meat and cheese ($4.75), the resultant sammy beats out any competitors for this price. On the Hill's bread and cheese options give you room for variety too, but at the end (beginning?) of the day, we recommend their havarti and sourdough.
