Well prepared and presented.
Reasonably priced (not more than $1/piece net, mixing nigiri, sashimi, and maki -- and preferably less).
And plenty of it -- think 30-40 pieces for me.
Optimally served with hot sake.
I've recently heard strongly positive reviews of Sushi Corner in Melrose, and though the reviews here are decidedly mixed, they appear to have a $30 All-You-Can-Eat option, which would be pretty damn perfect for me -- but I much prefer to indulge in such things in company of others...
Other options (including non-sushi, if the company's good) will be eagerly entertained; that said, I would prefer to be not more than 30 minutes from bed when we're done dining (takeout *is* an option), and need to be lying down by 11pm, if not earlier, as last night only delivered 3 hours restless sleep, between 4:00am and 7:30am...
I'll be passing through Melrose around 5:30 in any case, thence to Chelsea by about 6 if I've not built plans before leaving work, and moving on to the dinner hour shortly thereafter without doubt.
What say you?
