Just like other commenters say, it's weird but press on through the convenience store to one of the city's best sushi experiences. Normally sushi is rated in terms of quality, but the draw here is amplified by the creativity and variety of rolls -well beyond typical sushi offerings- plus the way they are *loaded* with ingredients. For your first visit, go when you have plenty of time because you WILL wait a while (it's totally worth it). When ordering, be forewarned that the rolls are thick and filling. After you've gotten a taste for their style of sushi you can can call ahead and pick up like most regulars.
