I wouldn't say that Sushi pop has great sushi (out of those I've tried, Yuki was the best), but for take-out (unless you're lucky enough to live near one of the few consistently good places, it's not bad). I live within reach of most of the Colegiales places. Its not the best barrio for Sushi but I've noticed a MAJOR decline in quality over the past two years from my favourite local takeouts - including up to a 50% decrease in the size of rolls, a major drop in rice quality, dryish fish, only salmon options and bits of bone in my sashimi! Sushi pop is no Yuki, but in the three months or so that we've been ordering it, its average quality is at least consistent, they have far more variety than my local takeouts, they deliver pretty much all over capital and we pay about 40% less than at our previous boney, soggy-riced takeout place.
