Cambridge / Harvard Square:
Felipe’s – even on an under $10 list, tamales, quesadilla, tacos. I have had combinations of all those. (I miss The Border).
Noch’s – 1 slice is usually enough, 2 to be stuffed.
Le’s – Bun (with cha gio), Grilled pork chop over rice, Bo luc lac if feeling spendy. It’s no Pho Pasteur but it’s decent enough. (I haven’t tried Bon Me yet.)
