How do you spell c-o-n-v-i-v-i-a-l-i-t-y? For starters, take a splendidly overstuffed bar on a Tuesday at Highland Kitchen, order up a paprika-dusted plate of mild, creamy, relish-studded deviled eggs ($3 gets you four plump halves) and nervously toss your name into Somerville's most hipster-approved weekly spelling bee. Seriously. But these lil' phosphorus-filled critters (also joined by 3-buck-biting cousins of housemade pickles and spiced nuts on the dinner menu) will give you proper brain fuel for the tourney (although that 2nd sazerac, sadly, will probably not).
