Aside from Wai Ying, Erra’s Ramen is one of our favorite food trip destination here in Manila. Erra’s is situated along Adriatico Street (near Coffee Bean Adriatico). It’s like an oversized sidewalk kainan. It serves Ramen and different pulutan (in a very affordable prize!). You’ll always spot foreigners eating who are probably staying in the opposite Backpackers hostel.
I’m not sure if it’s open 24 hrs but I think it’s open until dawn!
After a heavy meal, you can drop by the Eat.Cafe which is just near Erra’s. They serve chocnut pie (yes, made from chocnut) or try their other cakes.
