If there’s anybody looking for good American food (Macaroni and Cheese, Cheeseburgers, Philly Cheese Steaks, Pizza, etc.) and also some new fusion type food, go try Factory in Tainan, North District (just up the street from Red Wolf and Tainan Park). Owners/Chefs are real Americans and their food is just like how you would expect it in the US. They have a large selection of beer (American Crafts too) and of course, speak English.
Their address is:
630 Gong Yuan Road
