Boushey's now has take-away rotis from 'Groovy's Roti Hut.' I wish they'd leave out the water chestnuts, but other than that, it's very good. Quite fresh every time I've picked it up, too.
If downtown is more convenient for you, Boushey's on Elgin Street has a small selection of spices near the deli section and I've bought harissa there. The jarred version is better than the tube version which tastes a bit too metallic to me.
A few times I've been in and seen a GIANT stainless steel bowl with steaming kibbeh cooling on the counter (they cook these upstairs above the store). Very tempted to just pick it up and ask "How much for the whole deal?".
I highly recommend these...and they freeze/revive very well.
