They have a fairly decent selection of bagles and you can get a helping of cream cheese with them. They also do a wide range of other types of filled bagles and sandwhiches, as well as burgers, all day breakfast, burgers, sallads and pasta. Some of the restaurants also serve steak, like the one near the 101 area.
They also have a good selection of drinks to chose from, including hot and cold stuff as well as some more exotic imported things and rather decent milkshakes. You can find a map here and their website is located here. It’s not a gourmet place, but it’s a good place to go to on a weekend after a late night (early morning?) out in Taipei, as they’re guaranteed to be open.
