Waruguma was a great huge burrito, i are there on my first trip down...HOWEVER, i didnt ask the price BEFORE i ordered, and she charged me $20 freakin bucks! It was wonderful, but i definately got screwed since she believed me a tourist, and stupid me didnt ask first. I wont eat there again as i dont want to support a business that takes advantage of tourists (bad for the whole island), nor will i neglect to ask the price of something before hand.
Georges is WONDERFUL as well, i must say.
On Back street there was a little known shack called "popular", just near Super buy...i think she moved, but i cant find her now...she was INCREDIBLE. Really nice size burritos (not enormous, but good for a girl like me for lunch) for $2 BZ.
Also, Pan Dulce Bakery has ham and cheese roll up thingy's that are good for a small lunch for $1.5BZ
