If you're on the fence about trying Rosemont out, do yourself a favor and stay home.
By far the worst combination of food and overall restaurant experience in South End.
The food was cold, devoid of flavor and overpriced. The 'philly' that I ordered was $16 for two halves of medium sized sandwich role. It also was missing the cheese.
The atmosphere is a blend between a bad country music festival and a trashy dive bar.
On the plus side, it's close walking distance to dozens of other much better restaurants.
